On at least one platform the kernel prints a warning on resume saying "Unbalanced IRQ 37 wake disable". This is because enable_irq_wake in the suspend function is failing. This patch checks to see if the call to enable_irq_wake succeeded before calling disable_irq_wake.
While this looks okay, I'm wondering if this can also be fixed from the irq chip side by setting IRQCHIP_SKIP_SET_WAKE to .flags, given that the driver does not provide such function?
