I see your point, but I'd still rather have some generic way (since
the problem is actually common with controllers in legacy mode).

Something like

  if (hwif->irq == NO_IRQ) (*)
      hwif->irq = ide_get_legacy_irq(hwif);

Or maybe just de-obsolete one of the old "default" callbacks

(*) and please, don't compare with 0, 0 is a valid IRQ number on a
number of platforms !)
