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

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 21 Nov 2014 09:15:10 +0100

The dst_release() 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.
