Yeah, but the fear was that some hardware could either do a single INT
or (lots of) MSI{X}, and now you end up with (lots of) INT returned
from pci_intr_alloc() and can just use the first.
Does this not happen for real world hardware, or is the driver supposed to
check with pci_*_count() upfront?
I don't think pci_intr_alloc will ever return more than one INTx..
