This is due to a gruesome hack (IMO) in the genirq code (handle_irq_name())
which magically "knows" about the various types of IRQ handler, but doesn't
know about the MSI ones. It should be converted to a field in irq_desc, or
a callback or something.
I already had a whine about this then forgot about it, but it seems that
code can't be changed by whining at it ;)
