V4L/DVB (7129): tuner-simple: move device-specific code into three separate functions
Move the switch..case blocks with device-specific code from functions simple_set_tv_freq and simple_set_radio_freq ...into three new functions: simple_std_setup, simple_post_tune and simple_radio_bandswitch Signed-off-by: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
