4.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lyude Paul lyude@redhat.com
commit 611ce855420a6e8b9ff47af5f47431d52c7709f8 upstream.
Since actual hotplug notifications don't get disabled until nouveau_display_fini() is called, all this will do is cause any hotplugs that happen between this drm_kms_helper_poll_disable() call and the actual hotplug disablement to potentially be dropped if ACPI isn't around to help us.
