3.0-stable review patch. If anyone has any objections, please let me know.
------------------ From: Wu Fengguang <[email protected]> commit 832afda6a7d7235ef0e09f4ec46736861540da6d upstream. On DP monitor hot remove, clear DP_AUDIO_OUTPUT_ENABLE accordingly, so that the audio driver will receive hot plug events and take action to refresh its device state and ELD contents. Note that the DP_AUDIO_OUTPUT_ENABLE bit may be enabled or disabled only when the link training is complete and set to "Normal". Tested OK for both hot plug/remove and DPMS on/off.
