gspca_pac7302 module supports the webcam with usb id: 093a:2627.
It is a Genius FaceCam 300.
The module does not need any changes but listing the usb id along with a vertical flip flag.
The included patch adds this to the module source.

This patch adds v4l2_ctrl_new_int_menu() helper function which can be used
in drivers for creating standard integer menu control with driver-specific
menu item list. It is similar to v4l2_ctrl_new_std_menu(), except it doesn't
have a mask parameter and an additional qmenu parameter allows passing
an array of signed 64-bit integers as the menu item list.

Using the V4L2 core lock is a very robust method that is usually very good
at doing the right thing. But some drivers, particularly USB drivers, may
want to prevent the core from taking the lock for specific ioctls, particularly
buffer queuing ioctls.
The reason is that certain commands like S_CTRL can take a long time to process
over USB and all the time the core has the lock, preventing VIDIOC_DQBUF from
proceeding, even though a frame may be ready in the queue.
This introduces unwanted latency.
Since the buffer queuing commands often have their own internal lock it is
often not necessary to take the core lock. Drivers can now say that they don't
want the core to take the lock for specific ioctls.
As it is a specific opt-out it makes it clear to the reviewer that those
ioctls will need more care when reviewing.

Drivers can optionally set a pointer to a mutex in struct video_device.
The core will use that to lock before calling open, read, write, unlocked_ioctl,
poll, mmap or release.
Updated the documentation as well and ensure that v4l2-event knows about the
lock: it will unlock it before doing a blocking wait on an event and relock it
afterwards.
Ensure that the 'video_is_registered' check is done when the lock is held:
a typical disconnect will take the lock as well before unregistering the
device nodes, so to prevent race conditions the video_is_registered check
should also be done with the lock held.

This adds support for the KWorld PlusTV 340U and KWorld UB345-Q ATSC
sticks, which are really the same device. The sticks have an eMPIA
em2870 usb bridge chipset, an LG Electronics LGDT3304 ATSC/QAM
demodulator and an NXP TDA18271HD tuner -- early versions of the 340U
have a a TDA18271HD/C1, later models and the UB435-Q have a C2.
The stick has been tested succesfully with both VSB_8 and QAM_256 signals.
Its using lgdt3304 support added to the lgdt3305 driver by a prior patch,
rather than the current lgdt3304 driver, as its severely lacking in
functionality by comparison (see said patch for details).

This change adds support for Avermedia M733A. The original version for
linux 2.6.31 was sent to me from Avermedia, original author is unknown.
I ported it to current kernels, expanded and fixed key code handling for

test status analog (PAL-B):
- Sometimes picture is noisy, but it becomes crystal clear after
switching between channels. (happens for example at 687.25 Mhz)
- On a lower frequency (511.25 Mhz) the picture is always sharp, but
lacks colour.
- No sound problems.
- radio untested.
Digital:
- DVB-T/H stream reception works.
- Would expect to see some more channels in the higher frequency region.
Overall is the impression that sensitivity still needs improvement
both in analog and digital modes.

The term 'kernel number' is very vague, so replace it with the somewhat more
descriptive term 'device node number'.
In one place the local variable 'nr' was used to create the device node number
of the new device name. This has been replaced with the vdev->num field to
more clearly mark this as being the device node number and not the minor
number.
