My bad, I should have copied you, too. Thanks for having a look now.

The nak'ed series (https://lkml.org/lkml/2014/3/20/664) indeed already
included the "of: Add OF graph helper to get a specific port by id" and
"of: Add OF graph helpers to iterate over ports" patches, but Grant's
nak applied to the first patch, "of: Parse OF graph into graph
structure", which I then dropped.

See above. The other two patches have been uncontroversial. The
of_graph_get_next_endpoint and for_each_endpoint_of_node patches
fix an in-kernel API that was too easy to use incorrectly, and
the of_graph_get_port_by_id patch I can't remember being
commented on at all.

If you decide to apply them, please consider merging the tag and giving
your ack for it to be merged into the other subsystem trees, too.
