So that is this:

This is just kludgy. There are only two kernel-internal users of this function,
refactor the function signature and change the other callers over instead,
patch the drivers.
Take this opportunity to add some kerneldoc above the
pinconf_generic_dt_subnode_to_map() and give the function a
reasonable signature.
BTW: this is just for config settings for groups right? Not for muxing
I hope?
