#     Merge tag 'iommu-fixes-v5.6-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
#     
#     Pull iommu fixes from Joerg Roedel:
#     
#      - Compile warning fix for the Intel IOMMU driver
#     
#      - Fix kdump boot with Intel IOMMU enabled and in passthrough mode
#     
#      - Disable AMD IOMMU on a Laptop/Embedded platform because the delay it
#        introduces in DMA transactions causes screen flickering there with 4k
#        monitors
#     
#      - Make domain_free function in QCOM IOMMU driver robust and not leak
#        memory/dereference NULL pointers
#     
#      - Fix ARM-SMMU module parameter prefix names
#
