HP Envy AiO 32-a12xxx has an external amp that is controlled via GPIO
bit 0x04. However, unlike other devices, this amp seems to shut down
itself after the certain period, hence the OS needs to up/down the bit
dynamically only during the actual playback.
This patch adds the control of the GPIO bit via the existing pcm_hook
mechanism. Ideally it should be triggered at the actual stream start,
but we have only the state change at prepare/cleanup, so use those for
switching the GPIO bit on/off. This should be good enough for the
purpose, and was actually confirmed to work fine.

It was reported that the headphone output on ASUS UX430UA (SSID
1043:1740) with ALC295 codec is silent while the speaker works.
After the investigation, it turned out that the DAC assignment has to
be fixed on this machine; unlike others, it expects DAC 0x02 to be
assigned to the speaker pin 0x07 while DAC 0x03 to headphone pin
0x21.
This patch provides a fixup for the fixed DAC/pin mapping for this
device.

When switching virtio_pci_modern to use a helper for mappings we lost an
__iomem tag. We should restore it.
However, virtio_pci_modern is playing tricks by hiding an iomem pointer
in a regular vq->priv pointer. Which is okay as long as it's
all contained within a single file, but we need to __force cast
the value otherwise we'll get sparse warnings.

reset_work() in nvme-pci may hang forever in the following scenario:
1) A reset caused by a command timeout occurs due to a controller being
temporarily irresponsive.
2) nvme_reset_work() restarts admin queue at nvme_alloc_admin_tags(). At
the same time, a user-submitted admin command is queued and waiting
for completion. Then, reset_work() changes its state to CONNECTING,
and submits an identify command.
3) However, the controller does still not respond to any command,
causing a timeout being fired at the user-submitted command.
Unfortunately, nvme_timeout() does not see the completion on cq, and
any timeout that takes place under CONNECTING state causes a
controller shutdown.
4) Normally, the identify command in reset_work() would be canceled with
SC_HOST_ABORTED by nvme_dev_disable(), then reset_work can tear down
the controller accordingly. But the controller happens to return
online and respond the identify command before nvme_dev_disable()
should have been reaped it off.
5) reset_work() continues to setup_io_queues() as it observes no error
in init_identify(). However, the admin queue has already been
quiesced in dev_disable(). Thus, any following commands would be
blocked forever in blk_execute_rq().
This can be fixed by restricting usercmd commands when controller is not
in a LIVE state in nvme_queue_rq(), as what has been done previously in
fabrics.
```
nvme_reset_work(): |
nvme_alloc_admin_tags() |
| nvme_submit_user_cmd():
nvme_init_identify(): | ...
__nvme_submit_sync_cmd(): |
... | ...
---------------------------------------> nvme_timeout():
(Controller starts reponding commands) | nvme_dev_disable(, true):
nvme_setup_io_queues(): |
__nvme_submit_sync_cmd(): |
(hung in blk_execute_rq |
since run_hw_queue sees |
queue quiesced) |

queue_rq() in pci only checks if the dispatched queue (nvmeq) is ready,
e.g. not being suspended. Since nvme_alloc_admin_tags() in reset flow
restarts the admin queue, users are able to submit admin commands to a
controller before reset_work() completes. Commands submitted under this
condition may interfere with commands that performs identify, IO queue
setup in reset_work(), and may result in a hang described in the
following patch.
As seen in the fabrics, user commands are prevented from being executed
under inproper controller states. We may reuse this logic to maintain a
clear admin queue during reset_work().

When reporting a regression, users ideally should CC the subsystem and
its maintainers, as that will ensure they get aware of the regression
quickly. And if the culprit is known, they should also CC everyone who
signed if off; the text mentioned the latter in once place already, but
forgot to do so in two other areas where it's relevant.
While fixing this also remind readers to check the mailing list archives
for issues that need to be reported to a bug tracker, as someone might
have reported it by mail only.
All of this got triggered by a recent report where these changes would
have made a difference.

Perl, as with most scripting languages, is fairly flexible in how /
where you can define things, and it will (for the most part) do what you
would expect it to do. This however can lead to situations, like with
ktest, where things get muddled over time.
This pushes the variable definitions back up to the top, followed by
functions, with the main script executables down at the bottom, INSTEAD
of being somewhat mish-mashed together in certain places. This mostly
has the advantage of making it more obvious where things are initially
defined, what functions are there, and ACTUALLY where the main script
starts executing, and should make this a little more approachable.

Emacs and Vi(m) have different styles of dealing with perl syntax
which can lead to slightly inconsistent indentation, and makes the
code slightly harder to read. Emacs assumes a more perl recommended
standard of 4 spaces (1 column) or tab (two column) indentation.
Vi(m) tends to favor just normal spaces or tabs depending on what
was being used.
This gives the basic hinting to Emacs and Vim to do what is
expected to be basically consistent.
Emacs:
- Explicitly flip into perl mode, cperl would require
more adjustments
Vi(m):
- Set softtabs=4 which will flip it over to doing
indentation the way you would expect from Emacs

When desc->len is equal to chunk_size, it is legal. But when the

sctp: fix the race condition in sctp_destroy_sock in a proper way

As Or Cohen described:
If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock
held and sp->do_auto_asconf is true, then an element is removed
from the auto_asconf_splist without any proper locking.
This can happen in the following functions:
1. In sctp_accept, if sctp_sock_migrate fails.
2. In inet_create or inet6_create, if there is a bpf program
attached to BPF_CGROUP_INET_SOCK_CREATE which denies
creation of the sctp socket.
This patch is to fix it by moving the auto_asconf init out of
sctp_init_sock(), by which inet_create()/inet6_create() won't
need to operate it in sctp_destroy_sock() when calling
sk_common_release().
It also makes more sense to do auto_asconf init while binding the
first addr, as auto_asconf actually requires an ANY addr bind,
see it in sctp_addr_wq_timeout_handler().
This addresses CVE-2021-23133.

Normally SCTP_MIB_CURRESTAB is always incremented once asoc enter into
ESTABLISHED from the state < ESTABLISHED and decremented when the asoc
is being deleted.
However, in sctp_sf_do_dupcook_b(), the asoc's state can be changed to
ESTABLISHED from the state >= ESTABLISHED where it shouldn't increment
SCTP_MIB_CURRESTAB. Otherwise, one asoc may increment MIB_CURRESTAB
multiple times but only decrement once at the end.
I was able to reproduce it by using scapy to do the 4-way shakehands,
after that I replayed the COOKIE-ECHO chunk with 'peer_vtag' field
changed to different values, and SCTP_MIB_CURRESTAB was incremented
multiple times and never went back to 0 even when the asoc was freed.
This patch is to fix it by only incrementing SCTP_MIB_CURRESTAB when
the state < ESTABLISHED in sctp_sf_do_dupcook_b().

This reverts commit 12dfd78e3a74825e6f0bc8df7ef9f938fbc6bfe3.
This can be reverted as shutdown and cookie_ack chunk are using the
same asoc since commit 35b4f24415c8 ("sctp: do asoc update earlier
in sctp_sf_do_dupcook_a").

This reverts commit 7e9269a5acec6d841d22e12770a0b02db4f5d8f2.
As Jere notice, commit 35b4f24415c8 ("sctp: do asoc update earlier
in sctp_sf_do_dupcook_a") only keeps the SHUTDOWN and COOKIE-ACK
with the same asoc, not transport. So we have to bring this patch
back.

In enic_hard_start_xmit, it calls enic_queue_wq_skb(). Inside
enic_queue_wq_skb, if some error happens, the skb will be freed
by dev_kfree_skb(skb). But the freed skb is still used in
skb_tx_timestamp(skb).
My patch makes enic_queue_wq_skb() return error and goto spin_unlock()
incase of error. The solution is provided by Govind.
See https://lkml.org/lkml/2021/4/30/961.

The "resets" property is not present on R-Car Gen1 SoCs.
Supporting it would require migrating from renesas,cpg-clocks to
renesas,cpg-mssr.

Re-add the compatible value for R-Car H1, which was lost during the
json-schema conversion. Make the "resets" property optional on R-Car
H1, as it is not present yet on R-Car Gen1 SoCs.

Variable ret is set to zero but this value is never read as it is
overwritten with a new value later on, hence it is a redundant
assignment and can be removed.
Cleans up the following clang-analyzer warning:
drivers/of/overlay.c:1197:2: warning: Value stored to 'ret' is never
read [clang-analyzer-deadcode.DeadStores].
