Hmm, I wonder whether it is time to introduce helpers for these checks?
Something like iommu_domain_is_dma() is more readable.
Ha, I had exactly that at one point, except I think in the order of
iommu_is_dma_domain() :)
The end result didn't seem to give enough extra clarity to justify the
header churn for me, but I'm happy to be wrong about that if you prefer.
Cheers,
Robin.
