Subject[PATCH] SCSI-zfcp: Delete unnecessary checks before the function call "mempool_destroy"
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Mon, 16 Nov 2015 14:19:03 +0100

The mempool_destroy() function tests whether its argument is NULL
and then returns immediately. Thus the test around the calls is not needed.

This issue was detected by using the Coccinelle software.
