Check kfd-&gt;init_complete in kgd2kfd_iommu_resume, consistent with other
kgd2kfd calls. This should fix IOMMU errors on resume from suspend when
KFD IOMMU initialization failed.

Handle case when module is unloaded (kfd_exit) before a process space
(mm_struct) is released.

v2: Fixed potential race conditions by removing all kfd_process from
the process table first, then working on releasing the resources.

v3: Fixed loop element access / synchronization.  Fixed extra empty lines.

[Why]
Framedrops are observed while playing Vp9 and Av1 10 bit
video on 8k resolution using VSR while playback controls
are disappeared/appeared

[How]
Now ODM 2 to 1 is disabled for 5k or greater resolutions on VSR.

<title>drm/amd/display: Fix DP MST sinks removal issue</title>

[Why]
In USB4 DP tunneling, it's possible to have this scenario that
the path becomes unavailable and CM tears down the path a little bit late.
So, in this case, the HPD is high but fails to read any DPCD register.
That causes the link connection type to be set to sst.
And not all sinks are removed behind the MST branch.

[How]
Restore the link connection type if it fails to read DPCD register.

<title>drm/amd/display: Remove OTG DIV register write for Virtual signals.</title>

<content type='text'>
[WHY]
Hot plugging and then hot unplugging leads to k1 and k2 values to
change, as signal is detected as a virtual signal on hot unplug. Writing
these values to OTG_PIXEL_RATE_DIV register might cause primary display
to blank (known hw bug).

[HOW]
No longer write k1 and k2 values to register if signal is virtual, we
have safe guards in place in the case that k1 and k2 is unassigned so
that an unknown value is not written to the register either.

devm_regulator_get_enable_optional() returns -ENODEV if requested
