V4L/DVB (9048): add a general-purpose callback pointer to struct dvb_frontend
Remove tuner_callback pointers from tuner driver configuration and private state structures, replaced with a general-purpose callback pointer within struct dvb_frontend. A new parameter is added to the callback function, called component. This allows us to use this callback pointer by frontend components other than the tuner, if need be. So far, this is only used by tuner drivers. Signed-off-by: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
