when re-open or re-start (video_streamon), the q->curr would not be NULL in saa7134_buffer_queue(),
and all the qbuf will add to q->queue list,no one to do activate to start DMA,and then no interrupt
would happened,so it will be block.
In VIDEOBUF_NEEDS_INIT state, initialize the curr pointer to be NULL in the buffer_prepare().

In cases where the device does not actually provide a USB audio class *or*
vendor audio, do not load the driver that provides vendor audio support (such
as the KWorld 2800d). Otherwise, the /dev/audio1 device file gets created and
users get confused.
Also, reworks the logic a bit so that we don't try to inspect the register
content if the register read failed entirely.

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.
Thanks to Marcus Swoboda for reporting this and Udo Steinberg for testing
this patch.

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.

input devices
A bunch of V4L drivers generate BTN_0 instead of KEY_CAMERA key presses.
X11 is able to handle KEY_CAMERA automatically these days while BTN_0 is
not treated at all. Thus it would be of big benefit if the camera drivers
would consistently generate KEY_CAMERA. Some drivers (uvc) already do,
this patch updates the remaining drivers to do the same.
I only possess a limited set of webcams, so this isn't tested with all
cameras. The patch is rather trivial and compile tested, so I'd say it's
still good enough to get merged.

This adds support for DVB-T on the Leadtek DVR3100 H and should also get analog
TV capture from the tuner working properly as well.
DVB-T 6 MHz and 8 MHz have been tested and verified to work by Terry Wu of
Leadtek. DVB-T 7 MHz has also been verified working with a change developed by
Terry to the tuner-xc2028.c driver.
Special thanks go to Terry Wu <terrywu2009@gmail.com> of Leadtek who provided
the needed information and testing to get digital TV working for the Leadtek
DVR3100 H.

2. When call simple_fm_tune, read this byte from config and overwrite

Make the KWorld 2800d work properly. In this case, that means making the
profile more generic so that it works for both the Pointnix Intra-Oral USB
camera and the KWorld device.
The device provides the audio through a pass-thru cable, so we don't need
an actual audio capture profile (neither the K-World device nor the Pointnix
have an onboard audio decoder).
Thanks to Paul Thomas for providing sample hardware.
