Version 14, applied for next, thanks!
FYI; Since we are relying on an updated behaviour in the
pm_runtime_force_suspend|resume() helpers, which are queued as a patch
via Rafael's tree, I am going to withhold my pull-request for a few
days longer than usual, until Linus has picked up Rafael's
pull-request, for v5.20-rc1.
Kind regards
