Merge branch 'pci/virtualization' into next
* pci/virtualization: PCI: Document reset method return values PCI: Detach driver before procfs & sysfs teardown on device remove PCI: Apply Cavium ThunderX ACS quirk to more Root Ports PCI: Set Cavium ACS capability quirk flags to assert RR/CR/SV/UF PCI: Restore ARI Capable Hierarchy before setting numVFs PCI: Create SR-IOV virtfn/physfn links before attaching driver PCI: Expose SR-IOV offset, stride, and VF device ID via sysfs PCI: Cache the VF device ID in the SR-IOV structure PCI: Add Kconfig PCI_IOV dependency for PCI_REALLOC_ENABLE_AUTO PCI: Remove unused function __pci_reset_function() PCI: Remove reset argument from pci_iov_{add,remove}_virtfn()
