This breaks all existing in-tree and out-tree users.

DTS patches are independent, so you cannot fix in-tree that way. Anyway,
you cannot fix other users, so sorry, you are stuck with this or you
need some tricks (I once did for a qcom codec, but I don't know if this
is really the solution and my case was easier about the users).

Best regards,
Krzysztof
