From 0d09d3125642ac1f02937e577819dbc515291d93 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Thu, 3 Oct 2013 21:26:50 +0530 Subject: cpuidle: call cpuidle_get_driver() from after taking cpuidle_driver_lock There are a few cpuidle_get_driver() calls that aren't made under cpuidle_driver_lock which is incorrect. Fix them by calling cpuidle_get_driver() after taking cpuidle_driver_lock. Acked-by: Daniel Lezcano Signed-off-by: Viresh Kumar Signed-off-by: Rafael J.
