[PATCH] media: cx231xx: add support for TheImagingSource DFG/USB2pro

[Romain Reignier <r.reignier@robopec.com>]

Hello,

This is my first patch to the kernel so please be indulgent if I have done 
anything wrong and help me produce a better submission.

This is a patch to add the support for The Imaging Source DFG/USB2pro USB 
capture device. It is based on the Conexant CX23102 chip do the patch only 
consists in adding one entry in the devices list.

Note that the inputs for the Composite and S-Video are inverted in regard to 
most of the other boards.

I could test the Composite input that is working for several months in some of 
our products. But did not have the chance to try the S-Video input because I 
do not own any device with that standard (I have tried a simple Composite to 
S-Video cable but it does not work, even on Windows). So I have applied the 
same settings as the Windows driver.

I have created a page on the Wiki to describe the board:
https://www.linuxtv.org/wiki/index.php/The_Imaging_Source_DFG-USB2pro

Sincerely,

Romain Reignier
