[PATCH] UHCI: fix race in ISO dequeuing
This patch (as688) fixes a small race in uhci-hcd. Because ISO queues
aren't controlled by queue headers, they can't be unlinked. Only
individual URBs can. So whenever multiple ISO URBs are dequeued, it's
necessary to make sure the hardware is done with each one. We can't
assume that dequeuing the first URB will suffice to unlink the entire
queue.
