From: Rafael J. Wysocki Date: Wed, 15 Aug 2012 18:28:52 +0000 (+0200) Subject: PM / cpuidle: Make ladder governor use the "disabled" state flag X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=66804c13f7b79fb26cf4848ebac1e865b9aff65c;p=linux-beck.git 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.
