[Intel-gfx] [PULL] drm-misc-fixes

[Maxime Ripard]

Hi Daniel, Dave,

Here's this week drm-misc-fixes PR.

The two reverts for devm_drm_of_get_bridge are likely to bring more
reverts in the future.

Indeed, it introduced some code to fetch the panel automatically on
device tree child nodes as well, but that broke any driver with a child
node that wasn't a panel.

The reversion seems to be the best course of action right now, but it
was later pointed out that a number of drivers had been converted to
rely on the new behaviour, so those are likely to be broken now.

I'm not sure if it would be acceptable to merge them at this point, or
delay the merge drm-misc-fixes until those drivers are fixed?

drm-misc-fixes-2022-04-22:
Two fixes for the raspberrypi panel initialisation, one fix for a logic
inversion in radeon, a build and pm refcounting fix for vc4, two reverts
for drm_of_get_bridge that caused a number of regression and a locking
regression for amdgpu.
The following changes since commit 1ecc0c09f19f8e10a2c52676f8ca47c28c9f73c7:
