Deinitialize at reverse order when probe fails.
When init_sw_vars fails, rtl_deinit_core should not be called, specially
now that it destroys the rtl_wq workqueue.
And call rtl_pci_deinit and deinit_sw_vars, otherwise, memory will be
leaked.
Remove pci_set_drvdata call as it will already be cleaned up by the core
driver code and could lead to memory leaks too. cf. commit 8d450935ae7f
("wireless: rtlwifi: remove unnecessary pci_set_drvdata()") and
commit 3d86b93064c7 ("rtlwifi: Fix PCI probe error path orphaned memory").

rtl_wq is allocated at rtl_init_core, so it makes more sense to destroy it
at rtl_deinit_core. In the case of USB, where _rtl_usb_init does not
require anything to be undone, that is fine. But for PCI, rtl_pci_init,
which is called after rtl_init_core, needs to deallocate data, but only if
it has been called.
That means that destroying the workqueue needs to be done whether
rtl_pci_init has been called or not. And since rtl_pci_deinit was doing it,
it has to be moved out of there.
It makes more sense to move it to rtl_deinit_core and have it done in both
cases, USB and PCI.
Since this is a requirement for a followup memory leak fix, mark this as
fixing such memory leak.

Commit 2461c7d60f9f ("rtlwifi: Update header file") introduced a global
list of private data structures.
Later on, commit 26634c4b1868 ("rtlwifi Modify existing bits to match
vendor version 2013.02.07") started adding the private data to that list at
probe time and added a hook, check_buddy_priv to find the private data from
a similar device.
However, that function was never used.
Besides, though there is a lock for that list, it is never used. And when
the probe fails, the private data is never removed from the list. This
would cause a second probe to access freed memory.
Remove the unused hook, structures and members, which will prevent the
potential race condition on the list and its corruption during a second
probe when probe fails.

In ath12k_dp_rx_peer_frag_setup(), commit ea4192553850 ("wifi: ath12k: add primary
link for data path operations") checks whether a link is the primary link, and
returns directly if it isn't. In ML scenario where we have non-primary links created,
this results in leaking the michael_mic info since it is allocated by default but
could never be freed for a non-primary link.
Note that we can not move the might-sleep allocation after primary link check since
there we are in atomic context (due to spin lock). So keep the default allocation,
and then free it before return to fix this issue.

ath.git patches for v6.14
This development cycle featured multiple patchsets to ath12k to
support the new 802.11be MLO feature, although the feature is still
incomplete. Also in ath12k, there were other feature patches. In
ath11k, support was added for QCA6698AQ. And there was the usual set
of bug fixes and cleanups across most drivers, notable being the
addition of "noinline_for_stack" to some functions to avoid "stack
frame size" warnings when compiling with clang.

In commit 52250cbee7f6 ("mwifiex: use timeout variant for
wait_event_interruptible") it was noted that sometimes we seemed
to miss the signal that our host sleep settings took effect. A
10 second timeout was added to the code to make sure we didn't
hang forever waiting. It appears that this problem still exists
and we hit the timeout sometimes for Chromebooks in the field.
Recently on ChromeOS we've started setting the DPM watchdog
to trip if full system suspend takes over 10 seconds. Given
the timeout in the original patch, obviously we're hitting
the DPM watchdog before mwifiex gets a chance to timeout.
While we could increase the DPM watchdog in ChromeOS to avoid
this problem, it's probably better to simply decrease the
timeout. Any time we're waiting several seconds for the
firmware to respond it's likely that the firmware won't ever
respond. With that in mind, decrease the timeout in mwifiex
from 10 seconds to 5 seconds.

Currently, during mac80211 allocate and register single device is
considered for the registration. But, in future, during multi device
group abstraction is introduced, all the devices has to be combined
together as a single abstraction and then hardware should be allocated.
All the devices in the group should be combined together only if it
supports inter device mlo capability. The decision of whether to combine
the devices or not can be based on the mlo capability flag in
ath12k_hw_group.
By default, mlo_capable flag in the group would be set as false. During
QMI PHY capability exchange, only when we have more than one chip in the
group or if one chip, then that chip supports inter MLO, then mlo_capable
flag in the group will be enabled.
Add changes to introduce mlo_capable flag for device group and refactor
ath12k_mac_hw_allocate() api based on device group (ag) rather than
device (ab).

QMI host capability has the information regarding MLO parameters such as
device_id, MLO capability, group id and the information of each devices
involved in the group and sent immediately on QMI server arrive event.
Currently, only one device is involved in the group and hence, single
device information is sent as part of MLO capability of host.
But, in future when multi device group abstraction is introduced, host
should send all the device information involved in the group as part
of QMI MLO host capability rather than single device. Hence, sending
QMI host capability immediately on server arrive of a device might not
be ideal for multi device group abstraction as the details of other
devices in the group would not be available.
Hence, once QMI server arrive event is received, request for QMI PHY
capabilities of device, and defer the host capability send for that device.
After QMI PHY capability is received for all the devices in the group
trigger the host capability event for the deferred devices in the group.
Hence, add changes to defer the QMI host capability event until the device
group is ready and then resume the QMI exchange for all the device with
host capabilities.

Currently, hardware abstractions (ah) of different radio bands are tightly
coupled to a single device (ab). But, with hardware device group abstraction
(ag), multiple radios across different devices in a group can form different
combinations of hardware abstractions (ah) within the group. Hence, the mapping
between ah to ab can be removed and instead it can be mapped with struct
ath12k_hw_group (ag).
Current mapping between struct ath12k_hw (ah), struct ath12k_base (ab) and struct
ath12k_hw_group (ag):
+------------------------------------------------+
| +-------------------------------------+ |
| | +---------------+ +---------------+ | |
| | |ath12k_hw (ah) | |ath12k_hw (ah) | | |
| | +---------------+ +---------------+ | |

| | +-----------+ | +-----------+ | |
| | | ar (2GHz) | | | ar (5GHz) | | |
| | +-----------+ | +-----------+ | |
| | Dual band device-1 (ab) | |
| +-------------------------------------+ |
| ath12k_hw_group (ag) based on group id |
+------------------------------------------------+
After hardware device group abstraction moving ah array out of ab to ag:
+----------------------------------------------+
| +---------------+ +---------------+ |
| |ath12k_hw (ah) | |ath12k_hw (ah) | |
| +---------------+ +---------------+ |

| +-------------------------------------+ |
| ath12k_hw_group (ag) based on group id |
+----------------------------------------------+
This decoupling of struct ath12k_hw (ah) from struct ath12k_base (ab) and
mapping it to struct ath12k_hw_group (ag) will help in forming different
combinations of multi-link devices.

Currently, mac allocate/register and core_pdev_create are initiated immediately
when QMI firmware ready event is received for a particular device. With
hardware device group abstraction, QMI firmware ready event can be received
simultaneously for different devices in the group and so, it should not be
registered immediately rather it has to be deferred until all devices in the
group has received QMI firmware ready.
To handle this, refactor the code of core start to have registering within
ath12k_core_hw_group_start() and unregistering in ath12k_core_hw_group_stop().

Currently, single device is probed, and once firmware is ready, the device
is registered to mac80211. For Multi-Link Operation, different bands of
different devices or same device are part of a single wiphy and for
this, hardware device group abstraction is needed.
Hardware device group abstraction - when there are multiple devices (with
single radio or dual radio) that are connected by any means of interface
for communicating between them, then these devices can be combined
together as a single group using a group id to form a group abstraction
and register to mac80211.
The grouping information of multiple devices would be based on device tree
during device probe (will be implemented in future patches). If no such
information is available, then a single device will be part of group abstraction
and registered to mac80211, else multiple devices advertised in device tree are
combined and then registered to mac80211.
For device group abstraction, a base structure ath12k_hw_group (ag) and the
helpers are implemented. These helpers are used during device probe and mapping
the group to the devices involved.
An illustration of how multiple devices might be combined together in
future based on group id:
+------------------------------------------------------------------------+
| +-------------------------------------+ +-------------------+ |
| | +-----------+ | | +-----------+ | | +-----------+ | |
| | | ar (2GHz) | | | | ar (5GHz) | | | | ar (6GHz) | | |
| | +-----------+ | | +-----------+ | | +-----------+ | |
| | ath12k_base (ab) | | ath12k_base (ab) | |
| | (Dual band device) | | | |
| +-------------------------------------+ +-------------------+ |
| ath12k_hw_group (ag) based on group id |
+------------------------------------------------------------------------+
In the above representation, two devices are combined into single group
based on group id.
Add base code changes where single device would be part of a group with an
invalid group id forming an group abstraction. Multi device grouping will
be introduced in future.

At present, the mlo_capable_flags in ath12k_base is used to indicate whether
the chip supports inter (QCN9274) or intra (WCN7850) chip MLO. However, it’s
possible that the chip supports neither, especially with older firmware
versions. Additionally, if intra chip MLO is not supported, inter chip MLO will
also be non-functional. Therefore, having two separate flags for this is
unnecessary.
Therefore, rename this flag to single_chip_mlo_supp. At the same time convert
it into a bool data type. Also, get rid of the enums defined earlier.
For the QCN9274 family of chipsets, this will be set only when firmware
advertises the support during the QMI exchange.
For the WCN7850 family of chipsets, since the event is not supported,
assumption is made that single chip MLO is supported.

When hardware device group abstraction is introduced, a group abstraction is
registered to mac80211 rather than a particular single device. So we cannot
set the device registered when the QMI firmware ready event is received, only
after all the devices in group have received the event. To do that set and
unset ATH12K_FLAG_REGISTERED flag inside ath12k_mac_register() and
ath12k_mac_unregister() respectively.

value and set as an overflow value. Therefore, we added a check to limit
the calculated crystal_cap value. Additionally, we shrank the crystal_cap
adjustment according to specific CFO.

The original handling will iterate all active links under the given sta
and apply the changes to each. Now, stack tweaks ops from sta_rc_update
to link_sta_rc_update, which means targeting a given link. Then, our link
iteration looks redundant. So, refine it to apply the changes to the link
directly.

Currently, TX power is reported on interface/wdev level as
part of NL80211_CMD_GET_INTERFACE. With MLO, Multiple links
can be part of an interface/wdev and hence its necessary to
report the TX power of each link.
Add support to send tx power for all valid links of an MLD as
part of NL80211_CMD_GET_INTERFACE request.
As far as userspace is concerned, there is no behavioral change
for Non-ML Interfaces. For ML interfaces, userspace should fetch
TX power that is nested inside NL80211_ATTR_MLO_LINKS, similar to
how channel info(NL80211_ATTR_WIPHY_FREQ) is fetched.

If we got an unprotected action frame with CSA and then we heard the
beacon with the CSA IE, we'll block the queues with the CSA reason
twice. Since this reason is refcounted, we won't wake up the queues
since we wake them up only once and the ref count will never reach 0.
This led to blocked queues that prevented any activity (even
disconnection wouldn't reset the queue state and the only way to recover
would be to reload the kernel module.
Fix this by not refcounting the CSA reason.
It becomes now pointless to maintain the csa_blocked_queues state.
Remove it.

When hardware device group abstraction is introduced, the QMI firmware ready
event of different devices in a group can be received simultaneously. To
indicate the firmware ready event is completed for a particular device in a
group set a flag (ATH12K_FLAG_QMI_FW_READY_COMPLETE). This helps the upcoming
hardware recovery implementation for hardware device group abstraction.

Currently, one or more struct ath12k_hw is part of device (struct ath12k_base)
but in future, ath12k_hw would be part of device group (struct
ath12k_hw_group). Hence, num_hw under device would be moved to device group.
To facilitate above transition, add helper ath12k_get_num_hw() to get the
number of radios per device. In future, this helper will return the number of
radios in a device group.

In the upcoming hardware device group abstraction radios across different
devices can be grouped together to support multi-link operation and register as
a device group to mac80211.
Currently, ath12k_mac_allocate() and ath12k_mac_register() are part of
ath12k_core_start() and ath12k_core_pdev_create() respectively and are based on
per device (struct ath12k_base). These APIs can be decoupled and moved out to
ath12k_core_qmi_firmware_ready() itself. This refactor is helpful for device
group abstraction when mac80211 allocate and register will be changed from per
device (struct ath12k_base) to per device group (struct ath12k_hw_group).

Currently for single radio devices (ah->num_radio == 1)
ath12k_mac_op_add_interface() creates vdev and later hw scan and
assign_vif_chanctx uses the same. For MLO, vdev create request should carry ML
address which will not be known during ath12k_mac_op_add_interface() as vif
will be marked as ML only after links are added to it.
If hw scan is requested, the vdev will be deleted post hw scan and subsequent
assign_vif_chanctx call will create new vdev with ML address. But in certain
cases assign_vif_chanctx could be called without any prior hw scan request and
reusing the previously created vdev causes a non-ML vdev to be used for an ML
vif and firmware operates the vdev in non-ML mode.
Fix this by deferring vdev creation for interface until hw scan or
assign_vif_chanctx request is received from mac80211.

When a scan request is received, driver selects a link id for which the arvif
can be mapped. Same link is also used for getting the link conf address.
Currently, we return 0 as link id for a non ML vif, which is correct since that
is the default link id. Also when any of the link vif is active and the scan
request is for a channel in the active link we return its link id. But, when we
don't hit both of the above cases (i.e not a ML vif or no active link vif for
the channel is present) we currently return 0 as the link id.
Bu the problemis that this might not work out always, eg., when only one link
(eg. linkid = 1) is added to vif, then we won't find any link conf for link id
0 in the vif resulting in scan failure. During AP bringup, such scan failure
causes bringup issues. Hence avoid sending link id 0 as default. Rather use a
default link for scan and default link address for the same. This scan vdev
will either be deleted if another scan is requested on same vif or when AP is
broughtup on same link or during interface cleanup.

For a frame transmission for an ML vif, mac80211 mentions transmit link id in
the tx control info. Use it to convert the RA/TA to the corresponding link sta
and link vif address before enqueueing the frame for transmission.
For 802.3 data frames, always enqueue the frame on the primary (assoc) link id.
Firmware does the link selection, builds 802.11 header and therefore the address
translation too.
Also ensure right link vif is used for WMI based management transmission and
add comments to document when RCU read lock is held.
