[PATCH] ibmasm driver: redesign handling of remote control events
This patch rewrites the handling of remote control events. Rather than making
them available from a special file in the ibmasmfs, now the events from the
RSA card get translated into kernel input events and injected into the input
subsystem. The driver now will generate two /dev/input/eventX nodes -- one
for the keyboard and one for the mouse. The mouse node generates absolute
events more like a touch pad than a mouse.
