[SRU] [Unstable/OEM-5.14] [PATCH 0/1] Fix bogus HDMI audio interface

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1953208

[Impact]
Bogus HDMI audio can be selected as output, without any HDMI monitor
connected.

[Fix]
Consider 0 SAD as invalid ELD - no SAD means no audio.

[Test]
With the patch applied, no bogus HDMI audio can be found in GNOME's
setting app.

[Where problems could occur]
Basically none. No SAD means no PCM - so it has never worked before.
