Subject: Re: [PATCH 3/3] drm/i915: hot removal notification to HDMI audio
 driver

Update: Just tested DP and its working!

However, it's found that hot plug under X won't work...

The previous hot plug tests are done in KMS console which are all
fine: on re-inserting the monitor, ->mode_set will be called and
HDMI/DP audio will be re-enabled and ELD be transfered.

However when in X, ->mode_set won't be called at all.  Only
->get_modes and ->detect are called...

Thanks,
Fengguang
