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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



4.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Lyude Paul <lyude@xxxxxxxxxx>

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.
