      PCI: properly clean up ASPM link state on device remove · 3419c75e
      Alex Chiang authored
      We only want to disable ASPM when the last function is removed from
      the parent's device list. We determine this by checking to see if
      the parent's device list is completely empty.
      
      Unfortunately, we never hit that code because the parent is considered
      an upstream port, and never had an ASPM link_state associated with it.
      
      The early check for !link_state causes us to return early, we never
      discover that our device list is empty, and thus we never remove the
      downstream ports' link_state nodes.
      
      Instead of checking to see if the parent's device list is empty, we can
      check to see if we are the last device on the list, and if so, then we
      know that we can clean up properly.
