    iommu/amd: Cache pdev pointer to root-bridge · c1bf94ec
    Joerg Roedel authored
    At some point pci_get_bus_and_slot started to enable
    interrupts. Since this function is used in the
    amd_iommu_resume path it will enable interrupts on resume
    which causes a warning. The fix will use a cached pointer
    to the root-bridge to re-enable the IOMMU in case the BIOS
    is broken.
