    USB: EHCI: suppress unwanted error messages · 3a31155c
    Alan Stern authored
    This patch (as1096) fixes an annoying problem: When a full-speed or
    low-speed device is plugged into an EHCI controller, it fails to
    enumerate at high speed and then is handed over to the companion
    controller.  But usbcore logs a misleading and unwanted error message
    when the high-speed enumeration fails.
    The patch adds a new HCD method, port_handed_over, which asks whether
    a port has been handed over to a companion controller.  If it has, the
    error message is suppressed.
