Thanks for your patch, which is now commit 0ecd24a6d8b251eb ("ASoC:
hdmi-codec: dump ELD through procfs") in v6.15-rc1.
This causes the following failure on Salvator-XS:

asoc-audio-graph-card sound: ASoC: failed to register soundcard -12
asoc-audio-graph-card sound: probe with driver
asoc-audio-graph-card failed with error -12
And:
ALSA device list:
- #0: rcar-sound
+ No soundcards found.
So the card it tried to register is the first one?
Reverting the commit fixes the issue.
