Merge branches 'pci/aer', 'pci/misc' and 'pci/virtualization' into next
* pci/aer:
PCI/AER: Use list_first_entry_or_null() to simplify code
PCI/AER: Restore pci_ops pointer while calling original pci_ops
PCI/AER: Rename pci_ops_aer to aer_inj_pci_ops
* pci/misc:
PCI: Remove includes of asm/pci-bridge.h
PCI: Remove empty asm-generic/pci-bridge.h
ARM64: PCI: Remove generated include of asm-generic/pci-bridge.h
PCI: Remove includes of empty asm-generic/pci-bridge.h
PCI: Move pci_set_flags() from asm-generic/pci-bridge.h to linux/pci.h
PCI/PME: Restructure pcie_pme_suspend() to prevent compiler warning
PCI/PME: Remove redundant port lookup
PCI: Check device_attach() return value always
* pci/virtualization:
PCI: Add ACS quirk for all Cavium devices
