Subject: [PATCH 1/6] gpiolib: cdev: simplify linereq_free
Date: Wed, 13 Jul 2022 09:37:16 +0800	[thread overview]
Message-ID: <20220713013721.68879-2-warthog618@gmail.com> (raw)
In-Reply-To: <20220713013721.68879-1-warthog618@gmail.com>

The edge detector is only ever started after the line desc has been
determined, so move edge_detector_stop() inside the line desc check,
and merge the two checked regions into one.
