[linux-dvb] [PATCH 1/2] S2API: add multifrontend

Steve,

here is a patch which adds multifrontend to S2API (rev ffa9a0c644b3). It's based on 
the earlier patches by you and the mfe patches at Darron's website. Those patches
are quite old so I had to do a lot by hand without automatic patching -- so please check
it carefully.

Notes: somewhere along the line in the past
(a) videobuf-dvb.h:  struct dvb_adapter  *adapter; in videobuf_dvb changed to struct dvb_adapter adapter;
(b) videobuf-dvb.h:  videobuf_dvb_register gained an extra parameter short *adapter_nr.

I tested it with the HVR4000. Seems OK so far.

/dev/dvb/adapter0/frontend0: DVB-S/S2 (tested OK with new API, S,S2QPSK,S28PSK)
/dev/dvb/adapter0/frontend1: DVB-T (tested OK with old API)

The DVB-T part of the HVR4000 (cx22702) still needs additions so that it picks up
and uses the new API property cache (not hard as you know).

I see you are progressing rapidly (great!) so I thought I had better send this before
it's out of date.

You know this subject better than I, so I'll leave it up to you how to prioritise this, but
the recent messages in the ML indicate there is quite a lot of interest in multifrontend.

Regards,
Hans
