I agree, but with just one user (in a very odd way I do have to say, more on that on the review of that specific patch), it's hard to judge if this is useful are not, right? So, what happened to at least the Intel SOF driver usage? That was the original user of this bus (before it was renamed), surely that patchset should be floating around somewhere in Intel, right? thanks, greg k-h
