Better reverse the priority, with platform data checked first.

if (platp)
port->uartclk = platp->uartclk;
else {
ret = altera_uart_get_of_uartclk(pdev, port);
if (ret)
return ret;
}

Do you have a specific reasoning for this? I thought it might make sense
to do it in the same order as with the resources above, but I have no
problem changing it to the way you suggest.

Not quite sure. But I see some drivers follow this order, and I just followed, too.
