zeroed the memory and not to reference the commit?
I'd like to hear from Robin Murphy that arm smmu driver follows this as

I don't see SWIO or ARM64 IOMMU drivers getting impacted
In commit 518a2f1925c3
("dma-mapping: zero memory returned from dma_alloc_*"),
dma_alloc_coherent has already zeroed the memory.
So memset is not needed.
