Merge tag 'iommu-fixes-v4.14-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu

Pull IOMMU fixes from Joerg Roedel:

 - A comment fix for 'struct iommu_ops'

 - Format string fixes for AMD IOMMU, unfortunatly I missed that during
   review.

 - Limit mediatek physical addresses to 32 bit for v7s to fix a warning
   triggered in io-page-table code.

 - Fix dma-sync in io-pgtable-arm-v7s code

  iommu: Fix comment for iommu_ops.map_sg
  iommu/amd: pr_err() strings should end with newlines
  iommu/mediatek: Limit the physical address in 32bit for v7s
  iommu/io-pgtable-arm-v7s: Need dma-sync while there is no QUIRK_NO_DMA
