Latest version of https://patchwork.freedesktop.org/series/46815/ with some significant improvements:
- I finally figured out a clean way to do this entirely with runtime PM helpers, no avoiding grabbing refs required! - Since this new method removes the need for a lot of the other changes I made (although we probably still want those changes, but not for fixing these deadlocks) I've removed those now irrelevant patches from the series and will resend them on their own to make reviewing this go faster.
