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.
