While adding a preferred console handling for serial_core for serial port hardware based device addressing, Jiri suggested we constify name for add_preferred_console(). The gets copied anyways. This allows serial core to add a preferred console using serial drv->dev_name without copying it. Note that constifying options causes changes all over the place because of struct console for match().
