Subject: [PATCH] GPU-DRM-OMAP: Delete unnecessary checks before two function
 calls

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Wed, 4 Feb 2015 22:22:36 +0100

The functions framebuffer_release() and vunmap() perform also input
parameter validation. Thus the test around their calls is not needed.

This issue was detected by using the Coccinelle software.
