I don't do threaded patches very often so if I have messed something up,

Hi all,
After commit abe882a39a9c ("drm/amd/display: fix issue with eDP not

Hi all,
The introduction of this file in commit dbd249c24427 ("drm/amdgpu: add

drivers/gpu/drm/amd/amdgpu/amdgpu_ras.c:544:23: warning: implicit conversion
from enumeration type 'enum amdgpu_ras_block' to different
