V4L/DVB (4314): Set the Auxiliary Byte when tuning LG H06xF in analog mode
With the LG H06xF tuners, an auxiliary byte must be sent after the standard four-byte i2c sequence. The code that does this is currently in the wrong place, causing random bytes to be written to the tuner over i2c in the set_type function. This patch moves this code from set_type to default_set_tv_freq. Signed-off-by: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
