Bug Description
Please include the following upstream patch, which fixes an issue where an HDMI connection is being reported as a DVI issue.
[Original Report]
If when I start my laptop the HDMI wire is not connected, xrandr reports a
"DVI" interface, but if instead I start my laptop having the HDMI wire
connected an HDMI interface is reported.
This seemed a painless issue to me until I discover that the sound is not
streamed to the HDMI port when it is detected as DVI.
[Fix]
Alex Fiestas reported an issue with HDMI connector being misdetected as a
DVI unless he had something connected upon boot. By moving the decision
as to whether to use HDMI or DVI encoding for the HDMI capable output
until we probe the monitor means that we should avoid sending a HDMI
signal to a DVI monitor and also correctly detect hardware like Alex's.
