Hmm, looks good. But it makes me wonder if we should now try to remove the second call to tty_port_link_device()? Now we have a number of helpers that do that tty_port_link_device() call for the driver (eg tty_port_register_device_attr_serdev(), tty_port_register_device_attr(), and the just added uart_add_one_port()). But we also have drivers doing it by hand, and presumably we now have drivers that do it through multiple paths? I guess it's harmless, but it feels a bit odd. No? Linus
