Subject: [PATCH] net-RDS: Delete an unnecessary check before the function
 call "module_put"

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 2 Jul 2015 17:58:21 +0200

The module_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.
