I just thought of a 'third way'.
let IRQchips have their own struct irq_desc and have subdevice IRQs start from 0.
since those IRQs can only be raised by the parent chip I think this ought to work, and would eliminated the problem of a fixed size irq array... - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
