Merge tag 'pci-v5.17-fixes-5' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci

Pull pci fixes from Bjorn Helgaas:

 - Fix a merge error that broke PCI device enumeration on mvebu
   platforms, including Turris Omnia (Armada 385) (Pali Rohár)

 - Avoid using ATS on all AMD Navi10 and Navi14 GPUs because some
   VBIOSes don't account for "harvested" (disabled) parts of the chip
   when initializing caches (Alex Deucher)

* tag 'pci-v5.17-fixes-5' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci:
  PCI: Mark all AMD Navi10 and Navi14 GPU ATS as broken
  PCI: mvebu: Fix device enumeration regression
