Yes, mostly.  I've written the patch, but I was planning to target it
at 4.12 or 4.13 but not -stable.  It's mostly just a cleanup and has
no real power saving benefit since the RSTe timeouts are so absurdly
conservative that I doubt PS4 will happen in practical usage.  Perhaps
in suspend-to-idle?  (For suspend-to-idle, I suspect we should really
be using D3 instead.  Do we already do that?)
