This will allow the serial console, debuggers like kgdb, > and the IPMI serial driver to use one interface to the uart code and Its cheaper to allocate a uart_info that keep doing all the checks, at least for port->info. I can see why you want to avoid port->info->tty as a debugger can end up running before the tty layer and that would be hard to work around. For the other macros - the macros are more efficient than the equivalent inline code generation at least for some gccs. Do you really need any of this change but to check info->tty ?
