I think it's best to defer this patch (along with 21 and 22) until all
the others have been merged to make sure we don't regress. Other than
that it should be fine to apply the others in any order, right? Well,
maybe not any order, but at least the ASoC patches should be able to
go through the ASoC tree without impacting functionality, right?
