Subject: [PATCH] ASoC: Intel: Skylake: Delete an unnecessary check before the
 function call "release_firmware"

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 22 Jul 2016 18:58:14 +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.
