Subject: [PATCH 1/1] DRM-UDL: Deletion of an unnecessary check before the
function call "vunmap"
From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Wed, 19 Nov 2014 17:33:32 +0100
The vunmap() function performes also input parameter validation. Thus the test
around the call is not needed.
This issue was detected by using the Coccinelle software.
