Hi, Thanks for your review again, will fix what you noted. One idea for an improvment below though. * Andy Shevchenko <andriy.shevchenko@xxxxxxxxx> [221123 18:37]: > On Wed, Nov 23, 2022 at 10:28:25AM +0200, Tony Lindgren wrote: > > +EXPORT_SYMBOL(serial_port_get); > > Can we move these to namespace from day 1? 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
