Subject: [PATCH 1/2] SCSI-lpfc: Delete an unnecessary check before the function
 call "kfree"

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 5 Feb 2015 22:45:02 +0100

The kfree() 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.
