Subject: [PATCH] ethernet-synopsys: Delete an unnecessary check before
 of_node_put()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 7 Nov 2015 15:10:29 +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.
