    > set_irq_flags is ARM specific with custom flags which have genirq
    > equivalents. Convert drivers to use the genirq interfaces directly, so we
    > can kill off set_irq_flags. The translation of flags is as follows:

    > IRQF_VALID -> !IRQ_NOREQUEST
    > IRQF_PROBE -> !IRQ_NOPROBE
    > IRQF_NOAUTOEN -> IRQ_NOAUTOEN
    >
    > For IRQs managed by an irqdomain, the irqdomain core code handles clearing
    > and setting IRQ_NOREQUEST already, so there is no need to do this in
    > .map() functions and we can simply remove the set_irq_flags calls. Some
    > users also set IRQ_NOPROBE and this has been maintained although it is not
    > clear that is really needed. There appears to be a great deal of blind
