[patch 2.6.24-rc4] pcmcia stops updating dev->power.power_state

From: David Brownell
Date: Tue Dec 04 2007 - 15:53:04 EST


This stops the pcmcia core from using dev->power.power_state;
that field is deprecated (overdue for removal) and the only reason
to update it was to make the /sys/devices/.../power/state files
(now removed) work better.
