Looking at this I am wondering if we can actually to have

			unsigned long irq_flags;
			...
			irq_flags = acpi_dev_irq_flags(info.triggering, info.polarity,
						       info.shareable, info.wake_capable);
			*r = DEFINE_RES_NAMED(irq, 1, NULL, irq_flags);

as we don't need to duplicate IORESOURCE_IRQ.
