Subject: [PATCH 3/3] watchdog: wm8350: Simplify using devm_watchdog_register_device()
Date: Mon,  6 Mar 2023 18:09:01 +0100	[thread overview]
Message-ID: <20230306170901.2232323-4-u.kleine-koenig@pengutronix.de> (raw)
In-Reply-To: <20230306170901.2232323-1-u.kleine-koenig@pengutronix.de>

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().
