Subject: drm/nouveau: Remove duplicate poll_enable() in pmops_runtime_suspend()
Git-commit: 611ce855420a6e8b9ff47af5f47431d52c7709f8
Patch-mainline: v4.19-rc4
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
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.
