This patch marks those two functions as static:
static int videobuf_dvb_register_adapter(struct videobuf_dvb_frontends *fe,
static int videobuf_dvb_register_frontend(struct dvb_adapter *adapter,
Since MFE patches changed their calls by videobuf_dvb_register_bus.
To avoid having to declare the prototypes, the patch moves
videobuf_dvb_register_bus() to be after the declaration of the above functions
used there.

Jose reported:
I am using a Avermedia Volar X with af9015 driver(DVB-T).
The first time you use the card, first call reconfigure with MXL_QAM,
and when tune DVB-T it calls reconfigure with MXL_DVBT. But if you close
the frontend and open again, it calls reconfigure with MXL_QAM, but not
call reconfigure with MXL_DVBT because state->current_mode don't change
(is MXL_DVBT).

Christophe divulged the following:
"Since 8PSK (and higher mod) signals are very likely to have pilot symbols,
pilot_auto should start with pilot_on for 8PSK.
And since QPSK signals are unlikely to have pilot, pilot_auto should start
with pilot_off for QPSK.
Without the patch:
QPSK tuning delay: ~100ms
8PSK tuning delay: ~900ms
with patch:
QPSK tuning delay: ~100ms
8PSK tuning delay: ~100ms
"
This patch does as Cristophe asks. In emulated auto-pilot we
choose pilot-on for tuning PSK_8 and pilot-off for
tuning QPSK.

This adds I2S-ADC tvaudio mode as a formal method of audio
delivery.
This fixes one bug and adds fm audio via I2S-ADC on cards
that support it.
The bug occured before when I2S-ADC mode was initiated on
composite/s-video open but was then reset within 500ms
by the audio thread which used any previous audio tuning
details.

When moving from one frontend to another
an application could spawn multiple threads opening
the same new frontend and in some circumstances all of
these could become delayed waiting for the previous
frontend readers or previous frontend writer thread to
complete.
In this scenario the first thread will succeed on open
to bring the new frontend online but any others will return
EBUSY. This is a fault. If the first succeeds and all others
are on the same frontend then they should succeed also.

This patch improves the buffer handling in the sh_mobile_ceu driver.
Instead of marking all queued buffers as VIDEOBUF_ACTIVE the code now
marks queued-but-not-active buffers as VIDEOBUF_QUEUED and buffers
involved in dma as VIDEOBUF_ACTIVE. The code is also updated with
code to cancel active buffers, thanks to Morimoto-san.

cx23885 frontend allocation code needs to exist in the higher function,
and it also needs to ensure videobug is also correctly initialised
on a per frontend basis. This code uses the previous num_frontends
patch to safely init each future MFE frontend on a single tsport as
as safely as possible - given that we don't have any of those boards.
Again, better to add all of this safety code now, while the MFE patch
set is fresh in everyone mind, than to try and add it 12-24 months from
now, when the subject is cold.

requirements.
This adds line-in support on the 2 cards mentioned.
It is also apparent that there is an initial open
fault for line-in when opening composite/s-video.
This will be fixed later.
It was also noticed that the bit-field for audio
routing which was 2 bits needs an increase as
the WM8775 for example, allows a value 4 bits
wide for it's audio mux.

This add frontend R/W mutual exclusion.
Prior to this point in time it was possible to open both
frontends simultaneously which an MFE card cannot support.
In order to stop this, a delayed open is performed which
has the following function:
- Return EBUSY after a configurable amount of time
if a frontend is unavailable due to the other being
in use.
- Only allow opening of a frontend if the kernel thread
of the other has stopped.
This solution was chosen to allow switching between
frontends to work as seamlessly as possible. When both
frontends are actually opened simultaneously then one
will only open, but if quick switching is performed
between one of many then the new open will succeed in
a clean fashion rather than interrupting a kernel
thread.
