drm_edid_to_eld - build ELD from EDID : connector corresponding to the HDMI/DP sink : EDID to parse

Fill the ELD (EDID-Like Data) buffer for passing to the audio driver. Some ELD fields are left to the graphics driver caller:

• Conn_Type

drm_select_eld - select one ELD from multiple HDMI/DP sinks : the encoder just changed display mode : the adjusted display mode

It's possible for one encoder to be associated with multiple HDMI/DP sinks. The policy is now hard coded to simply use the first HDMI/DP sink's ELD.
