  [PATCH] memory: omap-gpmc: Delete an unnecessary check before the  function call "gpiochip_free_own_desc" SF Markus Elfring <elfring@users.sourceforge.net> - 2016-07-23 19:10 +0200

#1448976 — [PATCH] memory: omap-gpmc: Delete an unnecessary check before the function call "gpiochip_free_own_desc"

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sat, 23 Jul 2016 18:54:02 +0200

The gpiochip_free_own_desc() 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.
