Do you mean patch 4 or patch v4? If patch 4, of course it's useful, but
not for avoiding a regression with OF (case in which I drop all my claims
made earlier about fw_find_net_device_by_node), but rather to actually
get something working with actual ACPI (although perhaps not in this
series, you'll need to add ACPI IDs in the mv88e6xxx driver some time
later as well, maybe you could focus this series just on converting DSA
to play nice with fwnodes). If you're already thinking about the v4 of
this patch set, I'll respond to that in a separate email shortly.
