------------------------------------------------------
Subject: serial: fix serial_txx9 console initialization
From: Atsushi Nemoto <[EMAIL PROTECTED]>
Since commit 97d97224ff361e08777fb33e0fd193ca877dac28, serial_core
calls ->pm() on initialization even if the port was used for console.
This behaviour breaks serial_txx9 console since The serial_txx9 driver
initialize its port entirely on its ->pm() method if new state was 0.
This patch adds checking for oldstate value to fix this probelm.
