Subject[PATCH 6/9] [media] tm6000: Use common error handling code in tm6000_cards_setup()
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Thu, 14 Sep 2017 16:26:42 +0200

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

This issue was detected by using the Coccinelle software.
