Subject: [PATCH] hwmon-ntc_thermistor: Delete an unnecessary check before the function call "iio_channel_release"
Date: Mon, 18 Jul 2016 20:54:18 +0200	[thread overview]
Message-ID: <60ce7b63-99f8-67c2-319c-21b2d4199263@users.sourceforge.net> (raw)
In-Reply-To: <5317A59D.4@users.sourceforge.net>

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Mon, 18 Jul 2016 20:34:41 +0200

The iio_channel_release() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
