Both are similar, the code is in fact the same. I followed what Konrad
suggested in v3 to make a patch on top:

> Please use the recently-introduced header and depend on (and
make a patch atop)

https://lore.kernel.org/linux-devicetree/20230330165322.118279-1-me@dylanva=
nassche.be/T/#mab3c3421157acb0a4811dad5bb62d7349a9d4008

I can squash this patch in the FastRPC node one, that would make it
disappear. Let me know what you prefer and I will do it in v5 :)
