The IRQ line connected to RTC blocks are often shared with a timer device which request the IRQ with IRQF_NO_SUSPEND. Since the RTC drivers are correctly disabling IRQs when entering suspend we can safely request the IRQ with IRQF_SUSPEND_NOACTION so that irq core can suspend this specific handler.
