The multifrontend changes on cx88 assumed that all boards that use cx88-mpeg
supports DVB. This is not true. There also a few analog-only boards based on
Blackboard design that also uses cx88-mpeg. For those boards, there's no need
to allocate dvb frontends.
This patch fixes videobuf allocation for those devices.

inode is never used on video_ioctl2. Remove it and rename the function to
__video_ioctl2. This allows its usage directly as a callback at
fops.unlocked_ioctl.
Since we still need a callback with inode to be used with fops.ioctl,
this patch adds video_ioctl2() that is just a call to __video_ioctl2().
Also, this patch adds some comments about video_ioctl2 and __video_ioctl2
usage at v4l2-ioctl.h.

The inode parameter at v4l_compat_translate_ioctl() were just passed over several

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.

If we are already at the desired modulation, there is no need to reconfigure
the demod (at a tuning time cost)
Note that this change revealed that although the datasheet says the demod
starts out in VSB-8 mode, the first tuning was failing consistently unless
we went through the work of setting the registers. So add a field to denote
this case so we always do the enable_frontend call, even if the first tuning
request is for VSB-8.

If you instruct the tuner to change frequencies, it can take up to 2500ms to
get a demod lock. By performing a soft reset after the tuning call (which
is consistent with how the Pinnacle 801e Windows driver behaves), you get
a demod lock inside of 300ms

Fix deadlock problem in 2.6.27 caused by new USB core behavior in
response to a USB device reset request. With older kernels, the USB
device reset was "in line"; the reset simply took place and the driver
retained its association with the hardware. However now this reset
triggers a disconnect, and worse still the disconnect callback happens
in the context of the caller who asked for the device reset. This
results in an attempt by the pvrusb2 driver to recursively take a
mutex it already has, which deadlocks the driver's worker thread.
(Even if the disconnect callback were to happen on a different thread
we'd still have problems however - because while the driver should
survive and correctly disconnect / reconnect, it will then trigger
another device reset during the repeated initialization, which will
then cause another disconect, etc, forever.) The fix here is simply
to not attempt the device reset (it was of marginal value anyway).
