[ Upstream commit 63a06181d7ce169d09843645c50fea1901bc9f0a ]
devm_reset_control_get could fail, so the fix checks its return value and
passes the error code upstream in case it fails.

[ Upstream commit b9952f93cd2cf5fca82b06a8179c0f5f7b769e83 ]
[Why]
The kms_plane@plane-position-covered-pipe-*-planes subtests can produce
a sequence of atomic commits such that neither active_changed nor
mode_changed but connectors_changed.
When this happens we remove the old stream from the context and add
a new stream but the new stream doesn't have mode_changed=true set.
This incorrect programming sequence causes CRC mismatches to occur in
the test.
The stream->mode_changed value should be set whenever a new stream
is created.
[How]
A new stream is created whenever drm_atomic_crtc_needs_modeset is true.
We previously covered the active_changed and mode_changed conditions
for the CRTC but connectors_changed is also checked within
drm_atomic_crtc_needs_modeset.
So just use drm_atomic_crtc_needs_modeset directly to determine the
mode_changed flag.

[ Upstream commit f91813992c343272813e707343b50f8d06383659 ]
[Why]
The dc_gamma_type CUSTOM_GAMMA is used to represent degamma
mappings passed in by drm. This type of gamma must be interpolated
into a transfer function by apply_1d_lut. The line in
mod_color_calculate_degamma_params that handled this case
was erroneously removed.
[How]
For CUSTOM_GAMMA degamma, calculate the lut as before.

[ Upstream commit 49dc762cffd8305a861ca649e82dc5533b3e3344 ]
The driver should really call dm365_isif_setup_pinmux() through a callback,
but uses a hack to include a davinci specific machine header file when
compile testing instead. This works almost everywhere, but not on the
ARM omap1 platform, which has another header named mach/mux.h. This
causes a build failure:

[ Upstream commit 981fbe3da20a6f35f17977453bce7dfc1664d74f ]
Ref: https://bugzilla.kernel.org/show_bug.cgi?id=199323
Users are experiencing problems with the DVBSky S960/S960C USB devices
since the following commit:
9d659ae: ("locking/mutex: Add lock handoff to avoid starvation")
The device malfunctions after running for an indeterminable period of
time, and the problem can only be cleared by rebooting the machine.
It is possible to encourage the problem to surface by blocking the
signal to the LNB.
Further debugging revealed the cause of the problem.

Two i2c messages are sent to perform a reset in m88ds3103_set_frontend:
a. 0x07, 0x80
b. 0x07, 0x00
However, as shown in the capture, the regmap mutex is being handed over
to another thread (ts2020_stat_work) in between these two messages.
>From here, the device responds to every i2c message with an 07 message,
and will only return to normal operation following a power cycle.

both are processed before the regmap mutex is unlocked.

[ Upstream commit fdfa59cd63b184e1e96d51ff170fcac739bc6f6f ]
Commit 14f4eaeddabc ("media: dvbsky: fix driver unregister logic") fixed
a use-after-free by removing the reference to the frontend after deleting
the backing i2c device.
This has the unfortunate side effect the frontend device is never freed
in the dvb core leaving a dangling device, leading to errors when the
dvb core tries to register the frontend after e.g. a replug as reported
here: https://www.spinics.net/lists/linux-media/msg138181.html
media: dvbsky: issues with DVBSky T680CI
===
[ 561.119145] sp2 8-0040: CIMaX SP2 successfully attached

Si2168)...
[ 561.119174] sysfs: cannot create duplicate filename '/class/dvb/
dvb0.frontend0'
===
The use after free happened as dvb_usbv2_disconnect calls in this order:
- dvb_usb_device::props->exit(...)
- dvb_usbv2_adapter_frontend_exit(...)
+ if (fe) dvb_unregister_frontend(fe)
+ dvb_usb_device::props->frontend_detach(...)
Moving the release of the i2c device from exit() to frontend_detach()
avoids the dangling pointer access and allows the core to unregister
the frontend.
This was originally reported for a DVBSky T680CI, but it also affects
the MyGica T230C. As all supported devices structure the registration/
unregistration identically, apply the change for all device types.

[ Upstream commit 0ab34a08812a3334350dbaf69a018ee0ab3d2ddd ]
si2165_readreg8() may fail. Looking into si2165_readreg8(), we will find
that "val_tmp" will be an uninitialized value when regmap_read() fails.
"val_tmp" is then assigned to "val". So if si2165_readreg8() fails,
"val" will be a random value. Further use will lead to undefined
behaviors. The fix checks if si2165_readreg8() fails, and if so, returns
its error code upstream.

[ Upstream commit 459d69c407f9ba122f12216555c3012284dc9fd7 ]
There are some new e1000e devices can only be woken up from D3 one time,
by plugging Ethernet cable. Subsequent cable plugging does set PME bit
correctly, but it still doesn't get woken up.
Since e1000e connects to the root complex directly, we rely on ACPI to
wake it up. In this case, the GPE from _PRW only works once and stops
working after that. Though it appears to be a platform bug, e1000e
maintainers confirmed that I219 does not support D3.
So disable runtime PM on CNP+ chips. We may need to disable earlier
generations if this bug also hit older platforms.

When start_streaming was called both last_src_buf and last_dst_buf
pointers were set to NULL, but this depends on whether the capture
or output queue starts streaming.
When decoding with resolution changes in between the capture queue
has to restart streaming whenever a resolution change occurs. And
that would reset last_src_buf as well, which causes a problem if
the decoder was stopped by the application. Since last_src_buf
is now NULL, the LAST flag is never set for the last capture
buffer.

[ Upstream commit eec3d5efd16d13984a88396b685ae17462fb6d87 ]
[Why]
The plane_reset callback is subclassed but hasn't been updated since
the drm helper got updated to include resetting alpha related state
(state->alpha and state->pixel_blend_mode). The overlay planes
exposed by amdgpu_dm were therefore being rendered as invisible by

on overlays.
This caused regressions in igt@kms_plane_multiple@atomic-tiling-none

[How]
Reset the plane state values to their correct values as defined in
the drm helper.
This fixes the IGT test regression.

Somewhere in the atomic check reshuffle ABM got lost.
ABM is a crtc property (copied from a connector property).
It can change without a modeset, just like underscan.
[How]
In the skip_modeset branch of atomic check crtc updates,
copy over the abm property.

In certain cases we do link training when we don't have a backend.
[How]
In dc_link_set_preferred_link_settings(), store preferred link settings
first and then verify that the link is DP and the link stream's backend is
enabled. If either is false, then we will not do any link retraining.

[ Upstream commit f6ed6491d565c336a360471e0c29228e34f4380e ]
adma driver is using pm_clk_*() interface for managing clock resources.
With this it is observed that clocks remain ON always. This happens on
Tegra devices which use BPMP co-processor to manage clock resources,
where clocks are enabled during prepare phase. This is necessary because
clocks to BPMP are always blocking. When pm_clk_*() interface is used on
such Tegra devices, clock prepare count is not balanced till remove call
happens for the driver and hence clocks are seen ON always. Thus this
patch replaces pm_clk_*() with devm_clk_*() framework.

clang -Wuninitialized incorrectly sees a variable being used without
initialization:

This is clearly in dead code, as the condition leading up to it is always
false when CONFIG_NVME_FC is disabled, and the variable is always
initialized when nvme_fc_register_localport() got called successfully.
Change the preprocessor conditional to the equivalent C construct, which
makes the code more readable and gets rid of the warning.

The module was initializing completions whenever it was going to wait on
them, and not when the completion was allocated. This is incorrect
according to the completion docs:
Calling init_completion() on the same completion object twice is
most likely a bug [...]
Re-initialization is also unnecessary because the module never uses
complete_all(). Fix this by only ever initializing the completion a
single time, and log if the completions are not consumed as intended
(this is not a fatal problem, but should not go unnoticed).

[ Upstream commit d623dfd2836114507d647c9793a80d213d8bffe8 ]
The InfiniBand Architecture Specification section 10.6.7.2.4 TYPE 2 MEMORY
WINDOWS says that if the CI supports the Base Memory Management Extensions
defined in this specification, the R_Key format for a Type 2 Memory Window
must consist of:
* 24 bit index in the most significant bits of the R_Key, which is owned
by the CI, and
* 8 bit key in the least significant bits of the R_Key, which is owned by
the Consumer.
This means that the kernel should compare only the index part of a R_Key
to determine equality with another R_Key.

[ Upstream commit 167e535438ecc73d299340bb1269616432020dfb ]
The PLL parameters are computed by looping over the range of acceptable
M, N and E values, and selecting the combination that produces the
output frequency closest to the target. The internal frequency
constraints are taken into account by restricting the tested values for
the PLL parameters, reducing the search space. The target frequency,
however, is only taken into account when computing the post-PLL divider,
which can result in a 0 value for the divider when the PLL output
frequency being tested is lower than half of the target frequency.
Subsequent loops will produce a better set of PLL parameters, but for
some of the iterations this can result in a division by 0.
Fix it by clamping the divider value. We could instead restrict the E
values being tested in the inner loop, but that would require additional
calculation that would likely be less efficient as the E parameter can
only take three different values.

On the D3 SoC the LVDS PHY must be enabled in the same register write
that enables the LVDS output. Skip writing the LVEN bit independently
on that platform, it will be set by the write that sets LVRES.
