#     Merge tag 'iommu-fixes-v5.0-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
#     
#     Pull IOMMU fixes from Joerg Roedel:
#      "A few more fixes this time:
#     
#        - Two patches to fix the error path of the map_sg implementation of
#          the AMD IOMMU driver.
#     
#        - Also a missing IOTLB flush is fixed in the AMD IOMMU driver.
#     
#        - Memory leak fix for the Intel IOMMU driver.
#     
#        - Fix a regression in the Mediatek IOMMU driver which caused device
#          initialization to fail (seen as broken HDMI output)"
#     
#     * tag 'iommu-fixes-v5.0-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu:
