[PATCH 1/1] [media] V4L2: Deletion of an unnecessary check before the function call "vb2_put_vma"

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sun, 30 Nov 2014 23:10:51 +0100

The vb2_put_vma() 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.
