It seems to me that some other files missed,
in arch/powerpc/platforms/pasemi/msi.c:

         if (!mpic->irqhost->of_node ||
             !of_device_is_compatible(mpic->irqhost->of_node,
                                      "pasemi,pwrficient-openpic"))
                 return -ENODEV;

If you need more eyes to find all of them, please count me in :)

Thanks
