Subject: [PATCH 1/3] staging: wilc1000: Delete an unnecessary check before the
 function call "release_firmware"

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 24 Jul 2016 21:00:20 +0200

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.
