[PATCH] SGI Hotplug: Incorrect power status
This is a repost of a patch submitted by Prarit Bhargava on 01-19-06 that never got integrated. The get_power_status function is currently reporting a bitwise mapping of the slot if the slot is powered on. It should return 1 if powered on and 0 if powered off.
