Chris Wilson e85ade1f50 drm/i915: Hold reference to intel_frontbuffer as we track activity ... Since obj->frontbuffer is no longer protected by the struct_mutex, as we are processing the execbuf, it may be removed. Mark the intel_frontbuffer as rcu protected, and so acquire a reference to the struct as we track activity upon it.
