2) port is unused in all implementations. So it should be dropped.
3) can you make "c" an explicit u8?

The smh_putc function signature is defined by the uart_console_write helper. I don't think we can change it.

Ah. Of course. Then at least forward-declare struct uart_port here. So that it works also when someone decides to include the header outside serial.
