[PATCH] tty/serial: earlycon: Fix print for implied MMIO case

From: Kumar Gala
Date: Fri Oct 17 2014 - 05:01:22 EST


For the case in which we just provide an address as an argument to the
earlycon console type like:

earlycon=msm_serial_dm,0xf991e000

We would report this as an IO port based mapping and not as MMIO. Simple
fix to use the port->iotype to decide which message to print.
