From 5a50a01bf00c8191073fdf518e1af1e950ac3af5 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Wed, 24 Aug 2011 21:41:08 +0200 Subject: sh-sci / PM: Use power.irq_safe Since sci_port_enable() and sci_port_disable() may be run with interrupts off and they execute pm_runtime_get_sync() and pm_runtime_put_sync(), respectively, the SCI device's power.irq_safe flag has to be set to indicate that it is safe to execute runtime PM callbacks for this device with interrupts off.
