+What:	register_serial/unregister_serial
+When:	December 2005
+Why:	This interface does not allow serial ports to be registered against
+	a struct device, and as such does not allow correct power management
+	of such ports.  8250-based ports should use serial8250_register_port
+	and serial8250_unregister_port instead.
