Subject: [PATCH] pinctrl: Delete unnecessary checks before the function call
"pinctrl_unregister"
From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 5 Nov 2015 17:10:22 +0100
The pinctrl_unregister() 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.
