Merge conflicts:
- drivers/gpu/drm/amd/amdgpu/amdgpu_gem.c
	The switch to drm eu helpers in 8a206685d36f ("drm/amdgpu: use
	drm_exec for GEM and CSA handling v2") clashed with the
	cosmetic cleanups from 30953c4d000b ("drm/amdgpu: Fix style
	issues in amdgpu_gem.c"). I
	kept the former since the cleanup up code is gone.
- drivers/gpu/drm/amd/amdgpu/atom.c.
	adf64e214280 ("drm/amd: Avoid reading the VBIOS part number
	twice") removed code that 992b8fe106ab ("drm/radeon: Replace
	all non-returning strlcpy with strscpy") polished.
