Jean, I think this was a mistake in the original adaption of the
driver to the new irq stuff (which I didn't do). It mistakenly
returns IRQ_NONE if hw_unavailable is set in the interrupt handler
(wrong based on the "return IRQ_HANDLED" if in doubt rule). Does this
still happen with 0.13e? I've properly implemented the new IRQ stuff
there.
