Subject: [PATCH 1/1] fs-namei: Deletion of an unnecessary check before the
 function call "iput"

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 29 Nov 2014 17:00:21 +0100

The iput() 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.
