Subject: [PATCH][next] media: rcar-vin: fix return, use ret instead of zero

From: Colin Ian King <colin.king@...onical.com>

Currently the return error code is in ret is being assigned but not
used. It and should be returned by the return statement and currently
just 0 is being returned. Fix this.
