[PATCH 2/3] PM / Sleep: Correct inaccurate information in devices.txt

From: Rafael J. Wysocki
Date: Sat Nov 19 2011 - 19:55:23 EST


From: Rafael J. Wysocki <rjw@xxxxxxx>

The documentation file Documentation/power/devices.txt contains some
information that isn't correct any more due to code modifications
made after that file had been created (or updated last time). Fix
this.
