Subject: [PATCH 1/1] netlink: Deletion of an unnecessary check before the
 function call "__module_get"

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Tue, 18 Nov 2014 21:03:13 +0100

The __module_get() 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.
