This patch changes cx88_set_stereo to avoid resetting all of the audio
registers on stereo/mono change if the audio standard is A2, and set
only the AUD_CTL register. The benefit of this method is that it
eliminates the annoying clicking noise on setting the audio mode to
stereo or mono.
The driver had used the same method 1.5 years ago (and for FM radio it
still does), but a pretty big cleanup commit changed it to the
"complete audio reset" method, although the reason for this move was
not clear. (If somebody knows why it was necessary, please let me
know!)

The sole purpose of the audio thread is to detect if stereo transmission is
available, and if it is, then switch to stereo mode (and switch back, if it's
no longer available). This manual autodetection is useful for some audio
standards (e.g. A2) where cx88_get_stereo CAN detect stereo sound, but the
cx2388x chip CANNOT auto-detect stereo sound.
However, for other audio standards, the cx2388x chip CAN auto-detect the stereo
sound, so the manual autodetection in the audio thread is not needed. In fact,
it can cause serious problems because for some of these audio standards,
cx88_get_stereo CANNOT detect the presence of stereo sound. Besides that, if
the hardware automatically detects stereo/mono sound, you cannot set
core->audiomode_current to the real current audio mode on channel change.
With this patch, the manual autodetection is only used if audiomode_current is
known after a channel change (because of the initial mono mode), and
hardware-based stereo autodetecion is not applicable for the current audio
standard.

The patch implements reliable stereo and sap detection for the A2 sound
standard. This is achieved by processing the samples of the audio RDS fifo of
the cx2388x chip. A2M, EIAJ and BTSC stereo/sap detection is also possible with
this new approach, but it's not implemented yet. Stereo detection when alsa
handles the sound also does not work yet.

The fact that we now explicitly set fepriv->exit = 1 when the thread is
shutting down exposed an edge case where it was not being reset back to zero
once the thread went away in some cases. This resulted in failures in cases
where the frontend was closed, and then opened O_RDONLY, since in that case
the thread is not being restarted but it was checking the fepriv->exit flag.
Thanks to Thierry Lelegard, who and encountered and debugged a large portion
of the issue in the same twelve hours that I did (as well as testing my patch).

A race condition was detected in the case that putting the tuner to sleep takes
an unusually long period of time, combined with applications that quickly
close/open the dvb frontend.
The kaffeine channel scanner closes and reopens the dvb frontend between each
tuning attempt. If it takes an unusually longer period of time to put the
tuner to sleep (for example, the Pinnacle 801e takes 660 ms), the dvb_frontend
thread will still be in a running state (and hence fepriv->thread is still set)
but the fepriv->exit field will still be zero. As a result, if a
dvb_frontend_start() call arrives while the frontend thread is in the process
of terminating, the call will return 0 without actually starting a new thread.
This results in the tuning request being dropped.
To address this, mark fepriv->exit as soon as we know the thread is going to
be terminated, so that dvb_frontend_start() knows to start a new instance.
Problem encountered with Kaffeine 0.8.7 doing ATSC scanning against the
Pinnacle 801e tuner, in conjunction with new code to power down the xc5000

Since i2c autoprobing is no longer supported by v4l2 we need to make sure
that the i2c modules are linked before the v4l2 modules. The v4l2 modules
now rely on the presence of the i2c modules, so these must have initialized
themselves before the v4l2 modules.
The exception is the ir-kbd-i2c module, which is the only one still using
autoprobing. This one should be loaded at the end of the v4l2 module. Loading
it earlier actually causes problems with tveeprom. Once ir-kbd-i2c is no
longer autoprobing, then it has to move up as well.
This is only an issue when everything is compiled into the kernel.

Fix a regression caused by changeset 9133:64aed7485a43 - v4l: disconnect
kernel number from minor
Before the above changeset, ov511_probe used to allow forcing to use a
certain specific set of video devices, like:
modprobe ov511 unit_video=4,1,3 num_uv=3
So, assuming that you have 5 ov511 devices, and connect they one by one,
they'll gain the following device numbers (at the connection order):
/dev/video4
/dev/video1
/dev/video3
/dev/video0
/dev/video2
However, this was changed due to this change at video_register_device():
+ nr = find_next_zero_bit(video_nums[type], minor_cnt, nr == -1 ? 0 : nr);
With the previous behavior, a trial to register on an already allocated mirror
would fail, and a loop would get the next requested minor. However, the current
behavior is to get the next available minor instead of failing. Due to that,
this means that the above modprobe parameter will give, instead:
/dev/video5
/dev/video6
/dev/video7
/dev/video8
/dev/video9
In order to restore the original behavior, a static var were added,
storing the amount of already registered devices.
While there, it also fixes the locking of the probe/disconnect functions.

The frontend attachment code didn't handle cases where the frontend
partially failed to attach. For instance, when the demod was attached
successfully but the tuner driver wasn't compiled or fails to init for some
reason. In these cases we try to clean up the partial attachment and fail
instead of proceeding with a broken frontend.
If frontend registration fails, clean up with dvb_frontend_detach() rather
than just calling the frontend's main release method. The former does some
additional stuff, like release an attached tuner and take care of putting
symbols when dynamic binding is used.
In skystar2_rev23_attach() it's not necessary to set fc->dev_type, that
gets set before skystar2_rev23_attach() is called.
