[PATCH 3/3] hwmon: (ftsteutates) Use devm_watchdog_register_device()

From: Armin Wolf
Date: Fri Dec 23 2022 - 23:19:51 EST


Use devm_watchdog_register_device() to let devres take care
of unregistering the watchdog at device removal. Remove the
now pointless fts_remove() function.

Tested on a Fujitsu DS3401-B1.
