commit 3993546646baf1dab5f5c4f7d9bb58f2046fd1c1 upstream.
The kernel-doc for the of_irq_get[_byname]() is clearly inadequate in
describing the return values -- of_irq_get_byname() is documented better
than of_irq_get() but it still doesn't mention that 0 is returned iff
irq_create_of_mapping() fails (it doesn't return an error code in this
case). Document all possible return value variants, making the writing
of the word "IRQ" consistent, while at it...
