[PATCH 15/21] Restore tuning capabilities in v4l2 mxb driver

[mchehab@infradead.org]

From: Michael Hunold <hunold@linuxtv.org>
Date: 1142446742 \-0300

The behaviour of the all-in-one Video4Linux tuner driver apparently
changed.  It now wants to know the tv standard, otherwise it refuses to
tune.
Restore tuning functionality in my driver for the "Multimedia eXtension
Board".  The all-in-one tuner driver apparently changed its behaviour.
