[PATCH v2] [PATCH] drm/amdgpu: Initialise drm_gem_object_funcs for imported BOs

Tue Dec 8 20:16:15 UTC 2020
For BOs imported from outside of amdgpu, setting of amdgpu_gem_object_funcs
was missing in amdgpu_dma_buf_create_obj. Fix by refactoring BO creation
and amdgpu_gem_object_funcs setting into single function called
from both code paths.
Fixes: d693def4fd1c ("drm: Remove obsolete GEM and PRIME callbacks
from struct drm_driver")
v2: Use use amdgpu_gem_object_create() directly
