Commen= t # 1 on bug 10937= 5 from Rafa=C5=82 Mi=C5=82ecki 
For a comparison: behavior with the commit 262485a50fd4~1 (bef=
ore the
regression):

Before suspend:
> cat /sys/class/backlight/amdgpu_bl0/{actual_brig=
htness,brightness}
255
255

After resume:
> cat /sys/class/backlight/amdgpu_bl0/{actual_brig=
htness,brightness}
250
255

Looks like a problem with amdgpu restoring backlight after resume.
