Subject: [PATCH 1/1] net-ipvlan: Deletion of an unnecessary check before the
 function call "free_percpu"

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 29 Nov 2014 16:23:20 +0100

The free_percpu() 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.
