Jean-Francois Moine 8295d99ee5 V4L/DVB (8829): gspca: Have a clean kmalloc-ated buffer for USB exchanges. 
The USB buffer may be used for DMA and there may be a caching problem
if the buffer is part of the device structure.
Thanks to Alan Stern.

*Notes: * t613 + tas5130A
* * Focus to light do not balance well as in win.
* Quality in win is not good, but its kinda better.
* * Fix some "extraneous bytes", most of apps will show the image anyway
* * Gamma table, is there, but its really doing something?
* * 7~8 Fps, its ok, max on win its 10.
