Subject: [PATCH 1/1] video: fbdev-VIA: Deletion of an unnecessary check before
 the function call "framebuffer_release"

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 23 Nov 2014 16:30:05 +0100

The framebuffer_release() 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.
