In a bus remove function the passed device is always valid, so there is no need to check for it being NULL.
(Side note: The check for port being non-NULL is broken anyhow, because to_usb_serial_port() is a wrapper around container_of() for a member that is not the first one. So port can hardly become NULL.)
