From: Guenter Roeck <linux@roeck-us.net> [ Upstream commit 8dd29f19512cc75ee470d7bb8ec86af199de23a8 ] The driver registers the watchdog with devm_watchdog_register_device() but still calls watchdog_unregister_device() on remove. Since clocks have to be stopped when removing the driver, after the watchdog device has been unregistered, we can not drop the call to watchdog_unregister_device(). Use watchdog_register_device() to register the watchdog.
