Commit 47a8b0cc (Enable PCIe AER only after checking firmware support) wants to walk the PCI bus in the remove path to disable AER, and calls pci_walk_bus for downstream bridges. Unfortunately, in the remove path, we remove devices and bridges in a depth-first manner, starting with the furthest downstream bridge and working our way backwards. The furthest downstream bridges will not have a dev->subordinate, and we hit a NULL deref in pci_walk_bus. Check for dev->subordinate first before attempting to walk the PCI hierarchy below us.
