USB: FIX bitfield istl_flip:1, make it unsigned.
istl_flip is a signed bitfield of one bit so it can be -1 or 0. However in drivers/usb/host/isp1362-hcd.c:1103: finish_iso_transfers(isp1362_hcd, &isp1362_hcd->istl_queue[isp1362_hcd->istl_flip]); So if isp1362_hcd->istl_flip is set, the 2nd argument becomes &isp1362_hcd->istl_queue[-1], which is invalid.
