Hi,
The commit 407d1a51921e ("PCI: Create device tree node for bridge")
creates of_node for PCI devices.
During the insertion handling of these new DT nodes done by of_platform,
new devices (struct device) are created.
For each PCI devices a struct device is already present (created and
handled by the PCI core).
Creating a new device from a DT node leads to some kind of wrong struct
device duplication to represent the exact same PCI device.
This patch series first introduces device_{add,remove}_of_node() in
order to add or remove a newly created of_node to an already existing
device.
Then it fixes the DT node creation for PCI devices to add or remove the
created node to the existing PCI device without any new device creation.
Best regards,
Hervé
