The parameters are now iommu-indexes and not device-ids anymore. You
should reflect that in the prototypes here too.
Ahh.. thanks for pointing out. I missed this part.

Same here, and why do you need to declare the prototypes in two
different header files?
Hm.. actually good point. I will remove the unnecessary function
declarations in the amd_iommu_proto.h.
Thanks,
