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

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.
