But of_serial can be a loadable module, which means you still get into
trouble if you load it, even if the port was originally initialized
by legacy_serial.
Maybe the best solution would be for 824[15] to not claim compatibility
with 8250 at all then. If the device tree contains an entry that matches
what the generic driver looks for, it better be something that can
be handled by that driver.
