Subject: [PATCH] SCSI-csiostor: Delete an unnecessary check before the function
 call "release_firmware"

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 6 Feb 2015 19:10:25 +0100

The release_firmware() 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.
