I'd much prefer:

static inline irq_hw_number_t virq_to_hw (unsigned int virq)
{
	return irq_map[virq].hwirq;
}

I've grown to dislike the CR between the return type and the function
name (I used to do that too) and it seems that this opinion is shared by
Linus (there was an old thread on lkml about it).

Cheers,
Ben.
