Looks good to me. I applied both on top of next/soc before tagging the
branch for 4.13,
so this version is going to be what we merge.

I saw that David had another suggestion for simplifying it further.
That also looks
good, but it's less urgent, so please implement that as an add-on patch and send
it for 4.14, unless you decide there is a reason it needs to be
included in 4.13 as
well.

Thanks!
