What you should really be fixing is the commit message of patch 4,
that's what threw me off:
| As a preparation to switch the DSA subsystem from using
| of_find_net_device_by_node() to its more generic fwnode_
| equivalent, the port's device structure should be updated
| with its fwnode pointer, similarly to of_node - see analogous

| such as Clearfog GT-8K or CN913x CEx7 Evaluation Board.
There's no regression to speak of. DSA didn't work with ACPI before, and
fwnode_find_net_device_by_node() still works with the plain dev->of_node
assignment.
