I wouldn't bother too much about going into bus specific bits like irq_request(dev, ...). Well, actually, I _do_ think it's a good thing to pass the struct device to irq_request but that's a different issue completely.
I think bus types should provide bus specific helpers to obtain the struct irq *'s for a given device on that bus, but the API for requesting/freeing them shall remain generic.
