V4L/DVB (4400): Tda826x: Remove 0-byte I2C write; put tuner_ops info in static struct
Remove the 0-byte write that precedes 2-byte read. Move initialize the info field in the static tuner_ops definition, so that it doesn't need to be done manually. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
