Description Dave Jones 2008-03-29 23:04:52 UTC 
uvcvideo is one of the most common oopses reported at kerneloops..
http://www.kerneloops.org/oops.php?number=4254

The line that's causing the oops is in uvc_get_video_ctrl

        frame = &format->frame[ctrl->bFrameIndex - 1];
        ctrl->dwMaxVideoFrameSize = frame->dwMaxVideoFrameBufferSize;

It seems that frame ends up being a poison value causing the 2nd line to go boom

Dave-

The fix is trivial and in r199 in SVN.

Thanks,

Brandon

My testing last night confirms this. rev 200 should be in kernels built from
today (once I finish build testing.)

cheers, Kyle
