    Subject[PATCH 2/2] iommu: calling pci_fixup_iommu in iommu_fwspec_init
    Date
    Calling pci_fixup_iommu in iommu_fwspec_init, which alloc
    iommu_fwnode. Some platform devices appear as PCI but are
    actually on the AMBA bus, and they need fixup in
    drivers/pci/quirks.c handling iommu_fwnode.
    So calling pci_fixup_iommu after iommu_fwnode is allocated.
