This patch sets stream->urb_size as psize*npackets before calling uvc_alloc_urb_buffers, which may fix a possible failure of usb_buffer_free in case usb_buffer_alloc returns NULL. The patch is based on the ideas below: 1,If usb_buffer_alloc can't allocate a buffer sucessfully, uvc_free_urb_buffers will be called to free the allocated buffers, and stream->urb_size is required to be passed to usb_buffer_free; 2,uvc_free_urb_buffers can reset stream->urb_size. This patch is against linux-v2.6.31-next-20090926.
