[PATCH] drm/nouveau: Fix drm poll_helper handling
Commit cae9ff036eea effectively disabled the drm poll_helper by checking
the wrong flag to see if the driver should enable the poll or not:
mode_config.poll_enabled is only set to true by poll_init and it is not
indicating if the poll is enabled or not.
nouveau_display_create() will initialize the poll and going to disable it
right away. After poll_init() th...

[PATCH v4 1/8] drm/nouveau: Fix bogus drm_kms_helper_poll_enable() placement
Turns out this part is my fault for not noticing when reviewing
9a2eba337cace ("drm/nouveau: Fix drm poll_helper handling"). Currently
we call drm_kms_helper_poll_enable() from nouveau_display_hpd_work().
This makes basically no sense however, because that means we're calling
drm_kms_helper_poll_enable() every time we schedule the hotplug
detection work. This is also against the advice mentioned in

[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)

[PATCH v4 0/8] Fix connector probing deadlocks from RPM bugs
This is the latest version of
https://patchwork.freedesktop.org/series/46815/
With a bunch of fixes to the new fb_helper to prevent it from breaking
module loading/unloading with nouveau. Also; lots of documentation
fixes and one fix in response to a kbuild bot.

[PATCH v5 00/13] Fix connector probing deadlocks from RPM bugs
This is the latest version of https://patchwork.freedesktop.org/series/46815/
I moved everything out of fb_helper and back into nouveau, because it
seems that other drivers actually do have this handled already as far as
I can tell.

[PATCH v3 0/8] Fix connector probing deadlocks from RPM bugs
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!!!
