I just got a buildbot report that the above line needs 'irq.h' to be
included. But I wonder if we can't skip it with:

	flags = IRQF_TIMER;
	if (irq_disabled)
		flags |= IRQF_NO_AUTOEN;

> +		ret = devm_request_irq(dev, timer->ced.irq, rzn1_timer_interrupt,
> +				       IRQF_TIMER, timer->ced.name, timer);

and use 'flags' here?
