# Merge: f81fdd0c4ab7 a082121b55ba
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     Merge tag 'iommu-fixes-v5.8-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
#     
#     Pull iommu fixes from Joerg Roedel:
#     
#      - Fix a use-after-free of the device iommu-group. Found in the arm-smmu
#        driver, but the fix is in generic code.
#     
#      - Fix for the new Allwinner IOMMU driver to use the atomic
#        readl_timeout() variant in IO/TLB flushing code.
#     
#      - A couple of cleanups to fix various compile warnings.
#

#       iommu/arm-smmu: Mark qcom_smmu_client_of_match as possibly unused
#       iommu: Fix use-after-free in iommu_release_device
#       iommu/amd: Make amd_iommu_apply_ivrs_quirks() static inline
#       iommu: SUN50I_IOMMU should depend on HAS_DMA
#       iommu/sun50i: Remove unused variable
#       iommu/sun50i: Change the readl timeout to the atomic variant
