For the above:

	s/of_node:/BUS of_node:/

The debug printk is misleading. It is actually printing the BUS of_node:

	void pci_set_of_node(struct pci_dev *dev)
	{
		dev_dbg(&dev->dev, "%s: of_node: %pOF\n",
			__func__, dev->bus->dev.of_node);

		if (!dev->bus->dev.of_node)
			return;
	...

If I move it to the right place, e. g.:

	void pci_set_of_node(struct pci_dev *dev)
	{
		if (!dev->bus->dev.of_node) {
			dev_dbg(&dev->dev, "%s: BUS of_node is null\n",
				__func__, dev->bus->dev.of_node);
			return;
		}
		dev->dev.of_node = of_pci_find_child_device(dev->bus->dev.of_node,
							    dev->devfn);
		if (dev->dev.of_node)
			dev->dev.fwnode = &dev->dev.of_node->fwnode;

		dev_dbg(&dev->dev, "%s: of_node: %pOF\n",
			__func__, dev->dev.of_node);
	}

It will produce:

Which reflects the PCIe topology.

For the above:

	s/of_node:/BUS of_node:/

The debug printk is misleading. It is actually printing the BUS of_node:

	void pci_set_of_node(struct pci_dev *dev)
	{
		dev_dbg(&dev->dev, "%s: of_node: %pOF\n",
			__func__, dev->bus->dev.of_node);

		if (!dev->bus->dev.of_node)
			return;
	...

If I move it to the right place, e. g.:

	void pci_set_of_node(struct pci_dev *dev)
	{
		if (!dev->bus->dev.of_node) {
			dev_dbg(&dev->dev, "%s: BUS of_node is null\n",
				__func__, dev->bus->dev.of_node);
			return;
		}
		dev->dev.of_node = of_pci_find_child_device(dev->bus->dev.of_node,
							    dev->devfn);
		if (dev->dev.of_node)
			dev->dev.fwnode = &dev->dev.of_node->fwnode;

		dev_dbg(&dev->dev, "%s: of_node: %pOF\n",
			__func__, dev->dev.of_node);
	}

It will produce:

Which reflects the PCIe topology.
