This leaves an embedded notifier block on the PM notifier chain\nafter the watchdog device has been unregistered.\n\nA later suspend/resume notification can then call watchdog_pm_notifier()\nwith a stale watchdog_device pointer, or at minimum after wdd->wd_data has\nbeen cleared by watchdog_dev_unregister().\n\nUnregister the PM notifier before tearing down the watchdog device."
