updated ohci driver

[Sebastien R. <Seb...@sy...>]

I have corrected a bug which was preventing the direct iso dma
to user space to work properly when using several cameras 
simultaneously on the bus (see my previous mail for the 
announcement and the explanation on how to use it).

I have now dual acquisition of 640x480 YUV422 uncompressed frames
at 30 Hz, with a CPU load so small it doesn't even appear in the
'top' command ;-)

On the down side, I have sometimes some kernel oops when trying to
stop the user app using Ctrl-C... so be warned if you want to use
this feature (it is very stable while running though).

Any comment or bug report on the ohci driver is always welcome.

Cheers,
