[PATCH 0/2] drm/amdgpu: Avoid struct drm_gem_object.import_attach

[Thomas Zimmermann]

Avoid the use of struct drm_gem_object.import_attach to get the
object's dma-buf or test for an imported buffer. The import_attach
field in struct drm_gem_object is an artifact of the import process,
but should not be used otherwise.

The helper drm_gem_is_imported() tests if a GEM object's buffer
has been imported into the driver. The corresponding dma-buf is
referenced by the object itself. Both cases avoid import_attach.

Thomas Zimmermann (2):
  drm/amdgpu: Test for imported buffers with drm_gem_is_imported()
  drm/amdgpu: Use dma_buf from GEM object instance
