b905a2a133 [media] dvb_usb_v2: merge get_ts_config() to get_usb_stream_config()
Piggypag TS type callback to USB stream callback and change
callback name slightly to fit better.
Both of those are rather rare callback and has a relation. Transport
Stream, TS, is input stream and USB stream is output stream of
DVB USB bridge.

4edcf22bf2 [media] dvb_usb_v2: git rid of dvb_usb_adapter state variable
We can live without it easily.

Also USB data stream complete callback checks for feedcount
seems to be quite redundant so remove those also.

191f79a4d7 [media] dvb_usb_v2: use lock to sync feed and frontend control
There was synchronization problem when streaming was stopped.
Frontend was ran down before stream which causes problems.
Use mutex to synchronization. Now it looks like that:
LOCK
start frontend
UNLOCK
LOCK
start streaming
[...]
stop streaming
UNLOCK
LOCK
stop frontend
UNLOCK

6400a8c5af [media] dvb_usb_v2: change USB stream config logic
Initial / default USB stream configuration is now set always as a
dvb_usb_device_properties. Dynamic configuration is done top of
that if callback .get_usb_stream_config() exists. Default values
are set when callback is called so callback needs only change
values that are different than default.

In addition of that define two macros DVB_USB_STREAM_BULK() and
DVB_USB_STREAM_ISOC() for filling struct usb_data_stream_properties

ddee56943a [media] dvb_usb_v2: .read_mac_address() callback changes
Give DVB adapter as a parameter for callback. MAC address is
adapter property and it could be (at least in theory) there
is devices having multiple adapters and all has own MAC.

Also add error handling. If callback fails error is returned
which leads device unregister.

d32be21800 [media] dvb_usb_v2: do not check active fe when stop streaming
Do not check active frontend as it could be already shutdown.
Add some more debugs.

It turns out that device is put sleep earlier than streaming
is stopped in some cases. That is because streaming is running
different task and there is no locking.

Maybe some locking could be good idea to force stop streaming
before device is shut down. I can guess there could be problems
in someday cases like chip is sleep but streaming control is
requested after that...

e46c5b66da [media] dvb_usb_v2: move PID filters from frontend to adapter
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...

b6ecf8bb4e [media] dvb_usb_v2: add .get_ts_config() callback
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.
