Message-Id: <1424800730-32059-2-git-send-email-lorenzo.pieralisi@arm.com> Date: Tue, 24 Feb 2015 17:58:49 +0000 From: Lorenzo Pieralisi <lorenzo.pieralisi@....com> To: linux-pm@...r.kernel.org, linux-kernel@...r.kernel.org Cc: Lorenzo Pieralisi <lorenzo.pieralisi@....com>, "Rafael J. Wysocki" <rjw@...ysocki.net>, Daniel Lezcano <daniel.lezcano@...aro.org> Subject: [PATCH 1/2] drivers: cpuidle: remove stale irq disabling call in cpuidle_enter_freeze() On return from cpuidle_enter_freeze() irqs are re-enabled by the function caller (ie cpuidle_idle_call) in the idle loop. This patch removes a stale local_irq_disable() call and its stale comment in cpuidle_enter_freeze(), since they disagree and do not serve a useful purpose. Cc: Rafael J.
