[PATCH 3/3] watchdog: wm8350: Simplify using devm_watchdog_register_device()

From: Uwe Kleine-König
Date: Mon Mar 06 2023 - 12:10:53 EST


This allows to drop the .remove() function as it only exists to
unregister the watchdog device which is now done in a callback
registered by devm_watchdog_register_device().
