This seems a part of ABI.
ABI doesn't and shouldn't know anything about kernel internal types.
If I'm mistaken, one, who knows better the area, can submit a followup.

See above.
Nevertheless, there is an idea to add some wrappers to UUID framework to cover
cases when raw buffer is copied to UUID type or back and accompanying API.
At least btrfs expects such.
I will try to keep this in mind and convert ASoC stuff to the new API when it
appears in the upstream.
