    powerpc/eeh: Reduce use of pci_dn::node · 14db3d52
    Alexey Kardashevskiy 提交于
    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.
