Title:
display brightness level not retained over reboot with amdgpu

Status in linux-oem-6.11 package in Ubuntu:

Status in linux-oem-6.11 source package in Noble:
Fix Released
Bug description:
BugLink: https://bugs.launchpad.net/bugs/2090789
[Impact]
During boot up and resume the DC layer will reset the panel brightness
to fix a flicker issue. It will cause the `dm->actual_brightness` is
not the current panel brightness level. So we set the backlight level
with `dm->brightness` value after set mode.
[Fix]
Proposed fix
https://github.com/torvalds/linux/commit/4f26c95ffc21a91281429ed60180619bae19ae92
(in v6.12-rc7, and d83c747a1225d as in v6.11.8)
[Test Case]
1. Set panel brightness value to, say 5%, by pressing keyboard function keys.
2. Reboot and check if the actual panel brightness matches the setting.
[Where problems could occur]
This is to reset panel brightness value, not expecting anything could
go wrong.
[Other Info]
This has been in v6.12 and v6.11.8. SRU for oem-6.11 kernel for this
cycle only.
========== original bug report ==========
Upstream bug: https://gitlab.freedesktop.org/drm/amd/-/issues/3655:
Actually the issue happen when
1. Login to a system to console mode, set brightness to 5% (light -S 5 or
direct in sysfs), run compositor from command line. Screen brightness go up.
2. Turn brigtness down to 5% in wayfire screen, switch to text console and
back to wayfire - again screen brightness goes up.
3. Turn brightness to 5% in wayfire and then screen blanks at idle. Touch key
or mouse - screen again runs on the much higher brightness.
In all cases in the /sys/class/backlight/amdgpu_bl0 directory
brightness keep the value I set (5%) - but the actual brightness is
different. So system somehpw ignores the value in brightness and not
setting actual brightness the same but fill it with some default.
