041e:4022 from creative webcam nx pro, same as already supported 041e:401e
0ac8:0301 from generic zc0301 driver which supports many sensors

cx18: Simplify queue flush logic to prevent oops in cx18_flush_queues().
If accounting of a queue is in error, logic borrowed from ivtv will cause
an oops when flushing the queues for a stream. This change greatly
simplifies the queue flush logic, and sets the queue back to sane
defaults on a flush.

This patch fixes several small issues at vivi register routines:
1) minor and n_devs should be unsigned;
2) n_devs = 0 were not properly handled;
3) if n_devs specify a high number, the driver would just roll back and
won't register any device. The proper behaviour is to keep all succeded
devices registered;
4) both n_devs and minor were using 0 as permissions. Better to have
them with 0444.
With the current patch, if n_devs specify a very large value, it will
register all possible devices. For example, on a machine without any
other V4L drivers loaded, with this patch, we will have something like:
vivi: V4L2 device registered as /dev/video0
vivi: V4L2 device registered as /dev/video1
vivi: V4L2 device registered as /dev/video2
...
vivi: V4L2 device registered as /dev/video31
video_register_device_index: get_index failed
Video Technology Magazine Virtual Video Capture Board ver 0.5.0 successfully loaded.
5) The number of allocated devices on success is now kept at n_devs:
$ cat /sys/module/vivi/parameters/n_devs
32

The old Mediavision Pro Movie Studio legacy ISA V4L1 driver was found to
hang the boot during Ingo Molnar's testing of randconfig kernels. Have it
require a "pms.enable=1" kernel parameter to enable the driver when
builtin which avoids such problems.
This is a deprecated and, very likely, unused driver. Nothing changes
modular behaviour moreover.

If saa7134_init is run before v4l2_i2c_drv_init (tuner), then
saa7134_board_init2 will try to set the tuner type for devices that don't
exist yet. This moves tuner to before all of the device-specific drivers
so that it's loaded early enough on boot.

This patch adds a V4L2_CAP_SENSOR_UPSIDE_DOWN flag to the capabilities flags,
and sets this flag for the Philips SPC200NC cam (which has its sensor installed
upside down). The same flag is also needed and added for the Philips SPC300NC.
Together with a patch to libv4l which adds flipping the image in software this
fixes the upside down display with the SPC200NC cam.
