That one (and the second place where this happens later) look suspicious.
Do you need that change? Usually those includes tend to be alphabetically
sorted (which you destroy here).

When you _need_ that change that means that you probably use some things
from amd_iommu_types.h in amd_iommu_proto.h without including that header
there (which is a bug in amd_iommu_proto.h and must be fixed there).
Otherwise this change is just noise. So either way this change should not
happen IMHO.
