The commit 407d1a51921e ("PCI: Create device tree node for bridge") creates of_node for PCI devices. The newly created of_node is attached to an existing device. This is done setting directly pdev->dev.of_node in the code.
Even if pdev->dev.of_node cannot be previously set, this doesn't handle the fwnode field of the struct device. Indeed, this field needs to be set if it hasn't already been set.
device_{add,remove}_of_node() have been introduced to handle this case.
Use them instead of the direct setting.
