Subject[PATCH v3 0/8] Fix connector probing deadlocks from RPM bugs
Date
This is the next version of
https://patchwork.freedesktop.org/series/46815/

With a lot more thought put into it so as to avoid the potential
deadlock scenarios I missed. This also required fixing some bogus DRM
helper usage.

Try and deadlock me now, nouveau. I dare you!!!

Lyude Paul (8):
drm/nouveau: Fix bogus drm_kms_helper_poll_enable() placement
drm/nouveau: Enable polling even if we have runtime PM
drm/fb_helper: Introduce hotplug_suspend/resume()
drm/nouveau: Fix deadlock with fb_helper using new helpers
drm/nouveau: Use pm_runtime_get_noresume() in connector_detect()
drm/nouveau: Respond to HPDs by probing one conn at a time
drm/nouveau: Fix deadlocks in nouveau_connector_detect()
drm/nouveau: Call pm_runtime_get_noresume() from hpd handlers
