Thanks, I think that confirms my theory.

In this case, there's a warning on the routes:

[   22.364318] skl_n88l25_s4567 skl_n88l25_s4567: ASoC: Failed to add 
route iDisp3_out -> direct -> iDisp3 Tx

And we know that in 5.4 errors on routes caused the card registration to 
stop. I *think* the patch was  daa480bde6b3a9 ("ASoC: soc-core: tidyup 
for snd_soc_dapm_add_routes()")

This patch won't revert cleanly, can you try the following hack on v5.4 
to see if this improves the card registration? Thanks!
