From: Rafael J. Wysocki Date: Wed, 24 Aug 2011 19:41:08 +0000 (+0200) Subject: sh-sci / PM: Use power.irq_safe X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5a50a01bf0;p=linux-beck.git 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.
