   4 Subject: [PATCH 115/381] drm: Use the driver's gem_object_free function from
   5  CMA helpers.
   6
   7 VC4 wraps the CMA objects in its own structures, so it needs to do its
   8 own teardown (waiting for GPU to finish, updating bo_stats tracking).
   9 The other CMA drivers are using drm_gem_cma_free_object as their
  10 gem_free_object, so this should be a no-op for them.
