Yinghai Lu 29ed1f29b6 PCI: pciehp: Fix null pointer deref when hot-removing SR-IOV device ... Hot-removing a device with SR-IOV enabled causes a null pointer dereference in v3.9 and v3.10. This is a regression caused by ba518e3c17 ("PCI: pciehp: Iterate over all devices in slot, not functions 0-7"). When we iterate over the bus->devices list, we first remove the PF, which also removes all the VFs from the list. Then the list iterator blows up because more than just the current entry was removed from the list. ac205b7bb7 ("PCI: make sriov work with hotplug remove") works around a similar problem in pci_stop_bus_devices() by iterating over the list in reverse, so the VFs are stopped and removed from the list first, before the PF. This patch changes pciehp_unconfigure_device() to iterate over the list in reverse, too.
