[PATCH] hwmon-ntc_thermistor: Delete an unnecessary check before the function call "iio_channel_release"

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
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.
