    usb: gadget: fix wrong endpoint desc · e5b5da96
    EJ Hsu authored
    Gadget driver should always use config_ep_by_speed() to initialize
    usb_ep struct according to usb device's operating speed. Otherwise,
    usb_ep struct may be wrong if usb devcie's operating speed is changed.
    
    The key point in this patch is that we want to make sure the desc pointer
    in usb_ep struct will be set to NULL when gadget is disconnected.
    This will force it to call config_ep_by_speed() to correctly initialize
    usb_ep struct based on the new operating speed when gadget is
    re-connected later.
