To my knowledge we don't have such enumeration in the upstream (but it
may be done by third parties against any of our controllers enumerated
by UID, like Broxton or Gemini Lake).

That said, I still think that this is the right thing to do
independently, because logic currently is broken (we have tons of the
examples in the kernel where matching data is in use along with
platform supplied variants and there we check for matching data
first). Anyway, the proper use of this patch can be in the part of the
series which actually enables that kind of enumeration in the
upstream.

In any case I suppose Henning can test this for his purposes.
