Subject: legacy PC parports support parport->dev
From: Jean Delvare <khali@xxxxxxxxxxxx>
Give legacy parallel ports a platform device in the device tree.
This is a quick and dirty implementation; it doesn't actually convert the
legacy parport code to the device driver model (by splitting out probing from
device creation). But at least parallel port device drivers will finally have
a device to work with.
