Instead of creating a new mutex just for that variable I've figured I can reuse the existing dev->object_name_lock, especially since the new semantics will exactly mirror the flink obj->name already protected by that lock. v2: idr_preload/idr_preload_end is now an atomic section, so need to move the mutex locking outside.
