drivers/pci/quirks.c: irq_reroute_variant is dead code?

From: Jeremy Fitzhardinge

quirk_reroute_to_boot_interrupts_intel() goes to some effort to scan for
a bunch of Intel devices and set dev->irq_reroute_variant =
INTEL_IRQ_REROUTE_VARIANT. However, as far as I can see that's the only
reference to dev->irq_reroute_variant and INTEL_IRQ_REROUTE_VARIANT, so
the whole thing appears to have no effect.

Is it all dead code? Is there something else which should be there missing?

Thanks,
J
