Subject: drm/nouveau: Remove duplicate poll_enable() in pmops_runtime_suspend()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=611ce855420a6e8b9ff47af5f47431d52c7709f8;p=linux.git

drm/nouveau: Remove duplicate poll_enable() in pmops_runtime_suspend()

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.
