[PATCH 043/141] V4L/DVB (3269): Allow multiple tuner params in each tuner definition

[mchehab@infradead.org]

From: Michael Krufky <mkrufky@linuxtv.org>
Date: 1139300734 -0200

- allow multiple tuner params in each tuner definition.
- the correct tuner_params element will be chosen based on
  current video standard.
