Historically OF was only selectable by arch code, which usually also used IRQ_DOMAIN, thus making OF_IRQ and OF interchangeable for !SPARC.
Since OF is now a user selectable symbol, it is now easy to create a situation where OF=y and OF_IRQ=n, by not enabling IRQ_DOMAIN on e.g. x86. This causes linking errors as for a few functions the prototype guard was OF, which is too broad and does not catch all combinations. Recently added of_msi_configure is even missing a dummy implementation. The following three patches fix these issues by shuffling the prototypes and dummy implementations around (adding one where necessary), and make the guard for irq_of_parse_and_map more specific. Based on devicetree/next.
