[PATCH 1/2] [media] dmxdev: Use common error handling code in dvb_dmxdev_start_feed()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Tue, 26 Sep 2017 15:12:47 +0200

Add a jump target so that a bit of exception handling can be better reused
at the end of this function.

This issue was detected by using the Coccinelle software.
