It's not ARM-specific, though the overwhelming majority of users will be
ARM systems (it's an embedded PMIC) - I'll post a patch tomorrow
changing it to check for non-zero IRQ instead.  That makes other bits of
the driver easier, anyway.

That would be people on the ARM list.  Unless I misremember I first
heard about using NO_IRQ from the ARM list in connection with another
(much less ARM-specific) driver only within the past six months.
