I've already NACKed such a patch in the past, and I will carry on
NACKing it until all the other avenues (like properly tracking device
dependencies) have been explored and have been proven not to be fit for
purpose.

Rafael had proposed something around this subject last year, and I've
been repeatedly advising you to work with him and others to make it
happen. You can choose to ignore this advise, but that doesn't make this
patch an acceptable approach.

Thanks,
