usb: move struct usb_device->children to struct usb_hub_port->child
Move child's pointer to the struct usb_hub_port since the child device is directly associated with the port. Provide usb_get_hub_child_device() to get child's pointer. Signed-off-by: Lan Tianyu <tianyu.lan@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
