This reverts commit 18661234.

The video_device debug field has been renamed to dev_debug, resulting in
a compilation failure. As v4l2 debugging is supposed to be controlled
through a sysfs attribute created by the v4l2 core, there's no need to
duplicate debug control through a module parameter. Remove it.

The UVC spec is a bit vague wrt devices using bulk endpoints,
specifically, how to signal to a device to start streaming.

For devices using isoc endpoints, the sequence for start streaming is:
1) The host sends PROBE_CONTROL(SET_CUR) PROBE_CONTROL(GET_CUR)
2) Host selects desired config and calls COMMIT_CONTROL(SET_CUR)
3) Host selects an alt interface other then zero - e.g SELECT_ALTERNATE_INTERFACE(1)
4) The device starts streaming

However for devices using bulk endpoints, there must be *no* alt interface
other than setting zero. From the UVC spec:
"A VideoStreaming interface containing a bulk endpoint for streaming shall
support only alternate setting zero. Additional alternate settings containing
bulk endpoints are not permitted in a device that is compliant with the Video
Class specification."

So for devices using bulk endpoints, step #3 above is irrelevant, and thus
cannot be used as an indication for the device to start streaming.
So in practice, such devices start streaming immediately after a
COMMIT_CONTROL(SET_CUR).

In the uvc resume() handler, an unsolicited commit is sent, which causes
devices using bulk endpoints to start streaming unintentionally.

This patch modifies resume() handler to send a commit only if streaming
needs to be reestablished, i.e if the device was actually streaming before is
was suspended.

When receiving video it is very useful to be able to unpack the InfoFrames.
Logging is useful as well, both for transmitters and receivers.

Especially when implementing the VIDIOC_LOG_STATUS ioctl (supported by many
V4L2 drivers) for a receiver it is important to be able to easily log what
the InfoFrame contains. This greatly simplifies debugging.

The "i" variable is used as an offset into both the dev->vfd[] and the
dev->devtype->vdevs[] arrays.  The second array is smaller so we should
use that as a limit instead of ARRAY_SIZE(dev->vfd).  Also the original
check was off by one.

We should use a format string as well in case the ->name has any funny
characters and also to stop static checkers from complaining.

Remove tea575x-specific code from bttv and use the common driver instead.

Only set_frequency is implemented (signal/stereo detection or seek would
require more changes to bttv).

It works fine on Video Highway Xtreme (it actually makes the radio usable as
it currently cannot be tuned properly).

Miro/Pinnacle is untested but seems to be simple and should work.

However, I don't understand the Terratec Active Radio Upgrade code. The HW
seems to need IOR, IOW and CSEL signals that were taken from ISA bus on
older cards (IOR and IOW directly and CSEL from some address decoder) and
are emulated here using GPIOs. But the code manipulating these signals in
bttv seems to be broken - it never asserts the IOR signal. If anyone has
this HW, please test if I got that right.
