Such hard rules don't apply to regression fixes.  Patch
applied, thanks.

But I certainly would have required some positive testing for the
commit which introduced this problem!

I've added some verbosity to the commit message, so that people can
track where the problem was introduced, and exactly how this problem
arose, like so:

cs5520: add missing IRQ setup for the second port

This fixes a regression introduced by commit
86ccf37c6acd74cf7e4b7751ee045de19943c5a0 ("ide: remove pciirq argument
from ide_pci_setup_ports()")

ide_pci_setup_ports() would loop over the available ports, one
by one, recording IRQ numbers increasingly from the one passed
in as "pciirq".  The conversion only assigned the initial port's
IRQ, 14, but left the second one not setup.
