Yeah, they're plain duplications since you introduced dev.of_node.
I wonder what was the problem with using dev.archdata.of_node?
Why dev.of_node is better?

Also, by using dev.of_node directly you have to introduce ugly
#ifdefs in the non-OF code (as in i2c patch), which you don't
need with transparent archdata and accessors, which you've just
removed:
