Merge tag 'iommu-fixes-v6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/iommu/linux
Pull iommu fixes from Will Deacon:
"We're still resolving a regression with the handling of unexpected
page faults on SMMUv3, but we're not quite there with a fix yet.
- Fix NULL dereference when freeing domain in Unisoc SPRD driver
- Separate assignment statements with semicolons in AMD page-table
code
- Fix Tegra erratum workaround when the CPU is using 16KiB pages"
