Yeah I like, but plenty of review already so I wont bother.

I do wonder whether we should/could lift this one more level to
drm_gem_object, since cma/shmem gem helpers have this too.

But they have hand-rolled locking for it of dubious quality, and don't use
dma_resv_lock for any of this unfortunately. And I guess that would need
to be fixed first.
