#     Merge tag 'pci-v5.2-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci
#     
#     Pull PCI fix from Bjorn Helgaas:
#      "If an IOMMU is present, ignore the P2PDMA whitelist we added for v5.2
#       because we don't yet know how to support P2PDMA in that case (Logan
#       Gunthorpe)"
#     
#     * tag 'pci-v5.2-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci:
#       PCI/P2PDMA: Ignore root complex whitelist when an IOMMU is present
