[Intel-gfx] [PATCH v5 06/11] drm/i915: tidy initialisation failure paths (legacy, part 2)

[Dave Gordon]

After the last patch, there is only one caller of the trivial function
intel_destroy_ringbuffer_obj(), so we might as well fold it into the
caller.

v3:
   Don't bother to clear a pointer in an object about to be freed.
   [Chris Wilson]

v4:
   Don't bother to check for NULL pointer, as drm_gem_object_unreference
   can handle NULL [Chris Wilson]. This relies on 'base' being the very
   first member of 'struct intel_ringbuffer'!
