current_norm can only be used if there is a single device node since it is
local to the device node. In this case multiple device nodes share a single
tuner.

Add helper functions to make it easier to adapt drivers to vb2.
These helpers take care of core locking and check if the filehandle is the
owner of the queue.

This prepares struct video_device for easier integration with vb2.
It also introduces a new lock that protects the vb2_queue. It is up
to the driver to use it or not. And the driver can associate an owner
filehandle with the queue to check whether queuing requests are
permitted for the calling filehandle.

Add the necessary plumbing to make it possible to replace the switch by a

The ioctls ops can either be called directly, or by calling a small function

Add ".has_radio = 1" for BTTV_BOARD_MAGICTVIEW061 because there are
some CHP05x/CHP06x boards with a radio tuner.
I still have an analog Askey Magic TView card (CHP051, PCI 144f:3002)
which I use for radio only. This worked fine with kernel 2.6.37
(openSUSE 11.4), but no longer works with kernel 3.1.10 (openSUSE 12.1).
The reason apparently is that ".has_radio = 1" is missing in
bttv-cards.c for BTTV_BOARD_MAGICTVIEW061; when I add this line and
recompile the kernel, radio is working again. The line is still missing
in the latest git tree, for which I have generated the attached patch.
I can't test what will happen for CHP05x/CHP06x devices without radio;
however, it seems that other cards also have the problem that there are
some boards with radio and some without, so I hope that this can be
sorted out.

When video endpoint is configured as bulk, a ZLP is sent after every
video frames with size as multiple of 512 bytes. This is done so that
host can detect end of transfer and pass data for processing.
Still, frames that are multiple of 16K in size gets dropped. The ZLP
sent by camera is ignored by uvc_video_decode_bulk(). The makes sure
that the ZLP is not part of a video frame before ignoring it. If ZLP
follows a video frame, then it triggers completion callback.

Currently there are two different implementations (in the firmware) for
the QAM demodulator command: one takes 4 and the other takes 2
parameters. The driver shows an error in dmesg When using the
4-parameter command with firmware that implements the 2-parameter
command. Unfortunately this happens every time when chaning the
frequency (on DVB-C).
This patch simply makes configurable, how many command parameters will
be used. All existing drxk_config instances using the "drxk_a3.mc" were
updated because this firmware is the only loadable firmware where the
QAM demodulator command takes 4 parameters. Some firmwares in the ROM
might also use it. The drxk instances in the em28xx-dvb driver were also
updated to silence the warnings.
If no qam_demod_parameter_count is given in the drxk_config struct, then
the correct number of parameters will be auto-detected.

Commit 7a6f6c29d264cdd2fe0eb3d923217eed5f0ad134 (cx231xx: use
URB_NO_TRANSFER_DMA_MAP) was intended to avoid mapping the DMA buffer
for URB twice. This works for the URBs allocated with usb_alloc_urb(),
as those are allocated from cohernent DMA pools, but the flag was also
added for the VBI and audio URBs, which have a manually allocated area.
This leaves the random trash in the structure after allocation as the
DMA address, corrupting memory and preventing VBI and audio from
working. Letting the USB core map the buffers solves the problem.

Most calls to cx231xx_capture_start() already use the values from
TRANSFER_TYPE, but cx231xx_capture_start() and
cx231xx_initialize_stream_xfer() were hand coding the values.
Use the named values (81 is never passed in), and simplify
cx231xx_capture_start(), as the switch statements were identical and
pcb_config->config_num is a u8, so any non-zero config got the same
result.
