Subject: [PATCH 3/5] sh: superhyway: Simplify check in remove callback
Date: Tue, 27 Jul 2021 10:08:38 +0200	[thread overview]
Message-ID: <20210727080840.3550927-4-u.kleine-koenig@pengutronix.de> (raw)
In-Reply-To: <20210727080840.3550927-1-u.kleine-koenig@pengutronix.de>

The driver core only calls a remove callback when the device was
successfully bound (aka probed) before. So dev->driver is never NULL.

(And even if it was NULL, to_superhyway_driver(NULL) isn't ...)
