    Subject[PATCH 2/2 v2] sh-sci / PM: Use power.irq_safe
    Date
    From: Rafael J. Wysocki <rjw@sisk.pl>

    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 flags has to be used to indicate that it is safe
    to execute runtime PM callbacks for this device with interrupts off.
