Subject: [PATCH 2/2] [media] mn88473: One function call less in mn88473_init()
 after error detection

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 1 Dec 2014 23:15:20 +0100

The release_firmware() function was called by the mn88473_init() function even
if a previous function call "request_firmware" failed.
This implementation detail could be improved by the introduction of another
jump label.
