V4L/DVB (6978): tda18271: store frequency and bandwidth after successful tune
Store last tuned frequency & bandwidth after successful tune. Clean up tune functions -- remove pointer to tune function in state structure, instead call tune function based on priv->id. Signed-off-by: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
