Currently, EEH depends on device_node or pci_dev heavily. Unfortunately, SRIOV VFs are supported depending on pci_dn heavily, which is conflicting with EEH implementation. In order for better support EEH on SRIOV VF, the EEH is better to be changed a bit to depend on pci_dn, which is exactly what the patchset does.
The patchset is expected to merged after the patchset "EEH cleanup to remove chip layer for PowerNV", before "SRIOV patchset". The first two patches are extracted from SRIOV patchset to make this patchset self-contained.
