If interrupt is using as wakeup source/irq, after wake-up from suspend state, the interrupt handler will be handled. But, if interrupt is not used for wakeup source/irq, As your patch, we need to check the state on resume(). So, I think you need more condition to check the interrupt is whether wakeup source or not.
