Analog support for HVR-1250 has not been completed, but does exist for
the HVR-1800.

Since both cards use the same driver, it tries to create the analog
dev for both devices, which is not possible.

This causes a NULL error to show up in video_open and mpeg_open.

-Mark

Iterations through the cx23885_devlist must check for NULL
pointers as some supported devices only have DVB support at the moment.
Mark Jenks encoutered an Oops in a system with both an HVR-1250 and HVR-1800
installed.

Since the i2c driver ID will be removed in the near future we have to
modify the v4l2 debugging API to use the driver name instead of driver ID.

Note that this API is not used in applications other than v4l2-dbg.cpp
as it is for debugging and testing only.

Should anyone use the old VIDIOC_G_CHIP_IDENT, then this will be logged
with a warning that it is deprecated and will be removed in 2.6.30.

When the tuner modules were moved to common/tuners, a separate customize
option were added for tuners. However, the automatic selection of the
tuners were still using the older option.

This causes that the automatic selection to fail, if DVB_FE_CUSTOMISE is
selected. Also, since those tuners are now under MEDIA_TUNER_CUSTOMIZE
menu, if you unset MEDIA_TUNER_CUSTOMIZE, you can't manually select the
tuners.

This patch fixes this error by replacing DVB_FE_CUSTOMISE by
MEDIA_TUNER_CUSTOMIZE on all places were a tuner is selected.

The patch were generated by this small script:

for i in `find drivers/media -name Kconfig`; do
  cat $i|perl -ne 's/(MEDIA_TUNER.*)DVB_FE_CUSTOMISE/\1MEDIA_TUNER_CUSTOMIZE/; print $_' >a
  mv a $i
done

Also, manually reordered the tuner entries.

The kernel number of a v4l2 node (e.g. videoX, radioX or vbiX) is now
independent of the minor number. So instead of using the minor field
of the video_device struct one has to use the num field: this always
contains the kernel number of the device node.

I forgot about this when I did the v4l2 core change, so this patch
converts all drivers that use it in one go. Luckily the change is
trivial.

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.

This allows some cardcoded functions to be more flexible, and paves

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.

A detailed description from the original patches 2 years ago:

"The WinTV-HVR3000 has a single transport bus which is shared between
a DVB-T and DVB-S modulator. These patches build on the bus acquisition
cx88 work from a few weeks ago to add support for this.

So to applications the HVR3000 looks like this:
/dev/dvb/adapter0/fe0 (cx24123 DVB-S demod)
/dev/dvb/adapter0/fe1 (cx22702 DVB-T demod)

Additional boards continue as before, eg:
/dev/dvb/adapter1/fe0 (lgdt3302 ATSC demod)

The basic change is removing the single instance of the videobuf_dvb in
cx8802_dev and saa7134_dev(?) and replacing it with a list and some
supporting functions.

*NOTE* This branch was taken before v4l-dvb was closed for 2.6.19 so
two or three current cx88 patches appear to be reversed by this tree,
this will be cleaned up in the near future. The patches missing change
the mutex handing to core->lock, fix an enumeration problem."

It should be recognised that a number of people have been maintaining
this patchset. Significant levels of Kudos to everyone one involved,
including but not limited to:

Darron Broad
Fabio M. Di Nitto
Carlo Scarfoglio
Hans Werner

Without the work of these people, and countless others, my two year old
patches would of died on the Mercurial linuxtv.org vine a long time
ago.

TODO: Revise these patches a little further so that the need for
demux1 and dvr0 is optional, not mandatory on the HVR3000.

HISTORY (darron):
This is the last update to MFE prepared by Hans which is based
upon the `scratchpad' diff created by Carlo.
All MFE work prior to that point must be attributed to Fabio
who ported and maintained Steve's original patch up to that
time.

This pointer is passed into the tuner_callback function, which always
expects a pointer to fe->dvb->priv or i2c_adapter->algo_data.

This prevents future possible bugs in new drivers, such as using a "devptr"

b) The tuner callback previously checked the command 3 times:

2) To see if it was not the XC2028_RESET_TUNER
3) To see if it was the XC2028_RESET_TUNER
