From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx> Date: Sat, 29 Nov 2014 17:40:22 +0100 The functions xfs_blkdev_put() and xfs_qm_dqrele() test whether their argument is NULL and then return immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.
