I just saw the Telemetry driver today hit the list, so we have a user. No
objection. That patch series had some issues, so I'm waiting for a v2 which I
can apply and review properly.

Both of these are 4.4 candidates and I'd like them in next for as long as
possible, so please watch for Andriy's upcoming review. Thanks for sticking with
