-Subject: drm/atomic_helper: Disallow new modesets on unregistered connectors
-
-From: Lyude Paul <lyude@redhat.com>
-
-commit e96550956fbcd090629c0e2b5b8cded2eded2adf upstream.
-
-With the exception of modesets which would switch the DPMS state of a
-connector from on to off, we want to make sure that we disallow all
-modesets which would result in enabling a new monitor or a new mode
-configuration on a monitor if the connector for the display in question
-is no longer registered. This allows us to stop userspace from trying to
-enable new displays on connectors for an MST topology that were just
-removed from the system, without preventing userspace from disabling
-DPMS on those connectors.
-
-Changes since v5:
-- Fix typo in comment, nothing else
