From: Jani Nikula <jani.nikula@xxxxxxxxx> This patch has been added to the 3.18 stable tree. If you have any objections, please let us know. =============== [ Upstream commit ad692b46dbf122ef90aadce3b389ef64c90e861d ] 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.
