> next change its |struct usb_hub *| parameter will be changed to
> |struct usb_port *|, and becomes a non-static function that only
> references |struct usb_port|.

> port.h is only included from hub.h, as a subsequent patch will directly
> use fields from |struct usb_port| in a static inline helper in hub.h.
> The USB internal headers don't have header guards to help with this.
