Side note:

$ git grep -n -w setup_irq -- drivers/tty/
drivers/tty/serial/8250/8250_core.c:382:        .setup_irq      = univ8250_setup_irq,
drivers/tty/serial/8250/8250_port.c:2341:       retval = up->ops->setup_irq(up);

which rises a question of whether we need the setup_irq member in the
respective structure.
