  [PATCH] SCSI-lpfc: Delete unnecessary checks before the function call  "mempool_destroy" SF Markus Elfring <elfring@users.sourceforge.net> - 2015-11-17 09:50 +0100

#1270969 — [PATCH] SCSI-lpfc: Delete unnecessary checks before the function call "mempool_destroy"

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Tue, 17 Nov 2015 09:34:27 +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.
