[1][2]\n\nUse a kref to release the driver data to avoid use-after-free in\nmutex_unlock() when release() races with disconnect().\n\n[1] a51749ab34d9 (\"locking/mutex: Document that mutex_unlock() is\n                   non-atomic\")\n[2] 2b9d9e0a9ba0 (\"locking/mutex: Clarify that mutex_unlock(), and most\n                   other sleeping locks, can still use the lock object\n                   after it's unlocked\")",
