In this case we can easily pass the irqno into request_irq, allowing

I suspect this is the case for the majority of the non-trivial users
as well.
Not that easy, alas :) Save for weirdos like the mac drivers I
highlighted, it seems like most drivers in the non-trivial already pass
a useful pointer to request_irq().
But as I mentioned, most of the "non-trivial" uses are actually trivial
-- just not as simple as removing the 'int irq' argument. Most of the
time the irq number is used in non-critical ways like printk's. A few
times its used to index into a structure (something dev_id could replace).
