There's a few changes here:
* The rename, of course (this should also let us drop the clippy annotation
here)
* Return *mut bindings::drm_gem_object instead of
&Opaque<bindings::drm_gem_object> - the latter doesn't really have any
benefit and just results in conversion from the rust type to the C type
having to be more verbose than necessary.
