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)"
