Hi Mauro,

This is the pull request for the new vicodec driver. The cover letter is
here:

https://www.mail-archive.com/[e-mail]/msg133594.html

One request: the vicodec-codec.h header refers to Tom's report on the Fast Walsh
Hadamard Transform:

https://hverkuil.home.xs4all.nl/fwht.pdf

Can you copy this pdf and put it up somewhere on linuxtv.org and update the
link in the header so it points to linuxtv.org?

With all the activities ongoing it will be very useful to have this driver in
the kernel so we can test and verify APIs.

Regards,

	Hans
