Subject: [PATCH 3.14 212/238] media: cx18: fix kernel oops with tda8290 tuner

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Hans Verkuil <hans.verkuil@...co.com>

commit 6a03dc92cc2edfa2257502557b9f714893987383 upstream.

This was caused by an uninitialized setup.config field.

Based on a suggestion from Devin Heitmueller.
