Subject: [PATCH 1/2] [media] mn88473: Deletion of an unnecessary check before
 the function call "release_firmware"

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 1 Dec 2014 22:55:29 +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.
