Subject: [PATCH 1/1] SCSI-bfa: Deletion of an unnecessary check before the
 function call "vfree"

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 20 Nov 2014 23:43:17 +0100

The vfree() function performs also input parameter validation. Thus the test
around the call is not needed.

This issue was detected by using the Coccinelle software.
