+Subject: [PATCH] drm/edid: set ELD for firmware and debugfs override EDIDs
+
+If the user supplies EDID through firmware or debugfs override, the
+driver callbacks are bypassed and the connector ELD does not get
+updated, and audio fails. Set ELD for firmware and debugfs EDIDs too.
+
+There should be no harm in gratuitously doing this for non HDMI/DP
+connectors, as it's still up to the driver to use the ELD, if any.
