V4L/DVB (5558): Opera: use 7-bit i2c addresses
- the tuner i2c addr now without define (as wanted). - now 7 bit addr are used (the power_ctrl fkt ist ok so, because this is a raw write) - the addr >> 1 , addr << 1 is ok so, i think beause the read write is now taken from the last bit. - now i have no datasheet for the device, all taken from usb-logs Signed-off-by: Marco Gittler <g.marco@freenet.de> Signed-off-by: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
