The pci-rcar driver is enabled for compile tests, and this has
now shown that the driver cannot build without CONFIG_OF,
following the inclusion of f8f2fe7355fb "PCI: rcar: Use new OF
interrupt mapping when possible":

drivers/built-in.o: In function `rcar_pci_map_irq':
:(.text+0x1cc7c): undefined reference to `of_irq_parse_and_map_pci'

This driver /should/ be able to be built for just the platform case
so it sounds like f8f2fe7355fb stopped this but no-one has yet to
notice.

You mean include/linux/of_pci.h should provide a dummy version of
of_irq_parse_and_map_pci() returning 0 in case OF=n?

If I understand correctly, this patch was superceded by this one:

    "[PATCH] of/irq: provide int of_irq_parse_and_map_pci wrapper"

and you aren't expecting me to do anything.  Let me know if otherwise.

Yes, right. I checked that the build error was resolved by the above
mentioned patch.
