[PATCH v6 0/5] Fix connector probing deadlocks from RPM bugs
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)
