Subject: [PATCH] XFS: Delete unnecessary checks before the function call "xfs_qm_dqrele"

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 26 Jun 2015 11:05:41 +0200

The xfs_qm_dqrele() 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.
