Subject: [PATCH 1/1] [media] lirc_zilog: Deletion of unnecessary checks before
 the function call "vfree"

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 1 Dec 2014 19:49:39 +0100

The vfree() function performs also input parameter validation. Thus the test
around the call is not needed.

This issue was detected by using the Coccinelle software.
