V4L/DVB (3835): [PATCH] update pwc driver

Browse source 
Add v4l2 compatibility
Include the decompressor (legal problem has been resolv by Alan Cox)
Faster decoder and easier to maintain, optimize, ...
Can export to userland compressed stream
Support more cameras, lot of bugs are fixed.

See <file:Documentation/usb/philips.txt> for more information and
installation instructions.
Some newer logitech webcams are not handled by this driver but by the
Usb Video Class driver (linux-uvc).
The built-in microphone is enabled by selecting USB Audio support.
To compile this driver as a module, choose M here: the
module will be called pwc.

Say Y here in order to have the pwc driver generate verbose debugging
messages.
A special module options 'trace' is used to control the verbosity.
