powerpc/eeh: Reduce use of pci_dn::node
The pci_dn struct caches a OF device node pointer in order to access the "ibm,loc-code" property when EEH is recovering. However, when this happens in eeh_dev_check_failure(), we also have a pci_dev pointer which should have a valid pointer to the device node when pci_dn has one (both pointers are not NULL for physical functions and are NULL for virtual functions). This changes pci_remove_device_node_info() to look for a parent of the node being removed, just like pci_add_device_node_info() does when it references the parent node. This is the first step to get rid of pci_dn::node. Signed-off-by:Alexey Kardashevskiy <aik@ozlabs.ru> Signed-off-by:
