different values for get and set. And, yet more tricky part is the amplifier verbs. These aren't suitable with regmap caching, unfortunately.
We don't really *need* the cache, it just makes it easier to do resume and gives a bit of a performance boost.

My point is only that the design of HD-audio is so plain ugly :)
