Afaik Reported-by: should also have a Link:.
And IMO a Fixes: would also be fitting.

Hi amdgpu maintainers,
did you get a chance to look at the patch and the suspected bug?
Thanks,

Hi Hans!

Add a quirk infrastructure with which the valid backlight ranges can be
maintained as part of the kernel.

Not all platforms provide correct PWM backlight capabilities through ATIF.
Use the generic drm backlight quirk infrastructure to override the
capabilities where necessary.

While this patch introduces a new user for drm_edid_raw(),
if amdgpu proper gets migrated to 'struct drm_edid', that usage will go
away.
This is only compile-tested.
I have some more patches for the rest
still readable even in daylight.
Tested on a Framework AMD 13 BIOS 3.05 and Framework AMD 16.

Since commit ee6d3dd4ed48 ("driver core: make kobj_type constant.")
the driver core allows the usage of const struct kobj_type.
Take advantage of this to constify the structure definitions to prevent
modification at runtime.
