There is no USB match flag for used USB interface. It is rather
common there is multiple interfaces offering different services.
For example one for television and one for remote controller.

Calling usb_clear_halt() during device init is not correct.
2 of 7 AF9015 devices I have timeouts next USB control message
after usb_clear_halt(). It was originally performed between
tuner_attach() and rc_query() and likely not causing problems
since rc_query() is repeated continously. None could see it when
first rc_query() failed...

Secondly it was not called for .generic_bulk_ctrl_endpoint_response.

Adapter priv is not really needed, use device priv instead.
There is only driver or two using that.

Device caps are not needed. There was only "has I2C adapter"
capability defined. It is useless as we can see same just
checking existence of i2c_algo callback.

And also remove some totally not used at all variables.

Filtering given PIDs from the transport stream is done by the
DVB USB bridge. It is highly possible there is limitations what
kind of stream DVB USB bridge can PID filter, but it still does
not make sense to define filters for each frontend as frontend
could offer different stream types for different standards.

Likely new way is to enable / disable PID filters are needed to
make decision at runtime (callback). PID filters are quite legacy
stuff as those are aimed cut stream smaller to fit for the USB1.1...

Add new callback in order to resolve used TS (MPEG transport stream)
configuration. Normal TS is 188 byte payload only but there is
currently 204 byte TS and raw TS supported too.

Traditionally TS type was mapped as a frontend property but it
does not work no longer after we changed from MFE (multi-frontend)
to SFE (single-frontend). So it is not possible to map TS for the
given FE as there could be only one FE instead of multiple.
