Subject: [PATCH 3/3] [media] si2168: One function call less in si2168_init()
 after error detection

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Wed, 19 Nov 2014 23:23:15 +0100

The release_firmware() function was called in some cases by the
si2168_init() function during error handling even if the passed variable
contained still a null pointer. This implementation detail could be improved
by the introduction of another jump label.
