[PATCH 1/1] of-unittest: Deletion of an unnecessary check before the function call "of_node_put"

[SF Markus Elfring <elfring@users.sourceforge.net>]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Tue, 2 Dec 2014 13:54:00 +0100

The of_node_put() 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.
