In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: init return value in amdgputtmclear_buffer
Otherwise an uninitialized value can be returned if amdgpurescleared returns true for all regions.
Possibly closes: https://gitlab.freedesktop.org/drm/amd/-/issues/3812
(cherry picked from commit 7c62aacc3b452f73a1284198c81551035fac6d71)
