Subject: [PATCH] UBIFS: Delete unnecessary checks before the function call
 "iput"

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Wed, 4 Nov 2015 20:00:42 +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.
