Chris Wilson 65baf0ef04 drm/i915: Hold a ref to the ring while retiring ... As the final request on a ring may hold the reference to this ring (via retiring the last pinned context), we may find ourselves chasing a dangling pointer on completion of the list. A quick solution is to hold a reference to the ring itself as we retire along it so that we only free it after we stop dereferencing it.
