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!
