Subject[PATCH] PnP BIOS no-irq/IRQ0 bug
Here is a one-character patch which may be self-explanatory.
The irq should be initialized to -1 (i.e., "no irq") rather
than 0 (i.e., IRQ0) so that the irq field in the pci_dev will
be -1 and not 0 if the PnP BIOS returns an irq mask with no
bits set. // Thomas <jdthood_AT_yahoo.co.uk>
