Subject: [PATCH 1/1] HID: Wacom: Deletion of an unnecessary check before the
 function call "vfree"

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 29 Nov 2014 14:34:59 +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.
