Subject: [PATCH 1/2] ARM-OMAP2+: Delete an unnecessary check before the function
 call "omap_device_delete"

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 25 Jun 2015 13:00:11 +0200

The omap_device_delete() 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.
