of_irq_get() returns 0 iff irq_create_of_mapping() call fails. Returning

the kernel-doc as well...

So I think this is done this way because of the variation in NO_IRQ
definition across architectures.
I remember that NO_IRQ is "considered harmful" by Linus. Actually, I'm nit
sure what you mean, could you elaborate on that?
But then again, of_irq_get is
relatively new.
