Yes. My first impression was that with NR_IRQS dead valid_irq could
easily become. #define valid_irq(irq) ((irq) != 0) However thinking
just a little more since ultimately we will know which irqs have
something hooked up to them we might actually be able to say something
more interesting. So I guess actually having a valid irq function
makes sense. Instead of doing the idiomatic if (irq) logic inline.
