    Subject[PATCH 4.18 64/88] drm/nouveau: Remove duplicate poll_enable() in pmops_runtime_suspend()
    Date
    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.
