    USB: xhci: Stall handling bug fixes. · c92bcfa7
    Sarah Sharp authored
    Correct the xHCI code to handle stalls on USB endpoints.  We need to move
    the endpoint ring's dequeue pointer past the stalled transfer, or the HW
    will try to restart the transfer the next time the doorbell is rung.
    
    Don't attempt to clear a halt on an endpoint if we haven't seen a stalled
    transfer for it.  The USB core will attempt to clear a halt on all
    endpoints when it selects a new configuration.
