Hi,
commit 872b8f14d772 ("drm/amd/display: Validate backlight caps are
sane") was added to stable trees to fix a brightness problem on one
laptop on a buggy firmware but with how aggressive it was it caused a
problem on another.
Fortunately the problem on the other was already fixed in 6.12 though!
commit 87d749a6aab7 ("drm/amd/display: Allow backlight to go below
`AMDGPU_DM_DEFAULT_MIN_BACKLIGHT`")
Can that commit please be brought everywhere that 872b8f14d772 went?
Thanks!

This is confusing -- Mario used a wrong SHA.
The (correct) bad one is:
327e62f47eb5 drm/amd/display: Validate backlight caps are sane
and is present:
queue-5.15/drm-amd-display-validate-backlight-caps-are-sane.patch
queue-6.1/drm-amd-display-validate-backlight-caps-are-sane.patch
releases/6.10.13/drm-amd-display-validate-backlight-caps-are-sane.patch
releases/6.11.2/drm-amd-display-validate-backlight-caps-are-sane.patch
releases/6.6.54/drm-amd-display-validate-backlight-caps-are-sane.patch
The good one is:
87d749a6aab7 drm/amd/display: Allow backlight to go below
`AMDGPU_DM_DEFAULT_MIN_BACKLIGHT`
and is nowhere.
thanks,
