Subject: [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) I've removed those now irrelevant patches from
   the series and will resend them on their own to make reviewing this
   go faster.

Lyude Paul (5):
  drm/nouveau: Fix bogus drm_kms_helper_poll_enable() placement
  drm/nouveau: Remove duplicate poll_enable() in pmops_runtime_suspend()
  drm/nouveau: Fix deadlock with fb_helper with async RPM requests
  drm/nouveau: Use pm_runtime_get_noresume() in connector_detect()
  drm/nouveau: Fix deadlocks in nouveau_connector_detect()
