Hi Baoyou,

All your drm/amd patches seem fine to me, but again (as with the nouveau
driver patches before), I think it would make more sense to consolidate
them, and do a small number of patches such as

[PATCH 1/3] drm/amdgpu: add missing includes
[PATCH 2/3] drm/amdgpu: remove unused functions
[PATCH 3/3] drm/amdgpu: mark symbol static where possible

This is all one big driver, and I see no value in splitting it up
per file within the driver.
