Hi,

Thanks for your review again, will fix what you noted. One idea
for an improvment below though.

Assuming you mean EXPORT_SYMBOL_NS(), sure.

But we might be better off doing the following:

- Move already exported uart_add_one_port() and uart_remove_one_port()
from serial_core to serial_port as wrapper functions for serial_core

- Export new functions in serial_core for serial_core_register_port()
and serial_core_unregister_port() for serial_port to call

This would ensure both serial_core and serial_port modules are
always loaded when a hardware specific serial port driver is
loaded.

This should also leave out the need for serial_port_get() and
serial_port_put().

Regards,

Tony
