From 66804c13f7b79fb26cf4848ebac1e865b9aff65c Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Wed, 15 Aug 2012 20:28:52 +0200 Subject: PM / cpuidle: Make ladder governor use the "disabled" state flag For the mechanism introduced by commit cbc9ef0 (PM / Domains: Add preliminary support for cpuidle, v2) to work with the ladder governor, that governor should respect the "disabled" state flag added by that commit. Change the ladder governor accordingly. Signed-off-by: Rafael J.
