Subject: [PATCH 7/8] [media] videobuf-dma-sg: Delete an unnecessary return
 statement in videobuf_vm_close()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 26 Dec 2016 21:09:01 +0100

The script "checkpatch.pl" pointed information out like the following.

WARNING: void function return statements are not generally useful

Thus remove such a statement here.
