The same regression hits Intel SOF/HDA: on a ThinkPad E16 Gen3 (Arrow
Lake, Core Ultra 7 255H, Conexant SN6140) no internal card is registered
on v7.4-rc2, with
skl_hda_dsp_generic skl_hda_dsp_generic: ASoC: Failed to add route ...
Analog Playback and Capture: fail to add hda routes, ret -19
This also looks like the regression reported for Meteor Lake here:

With this patch on top of v7.4-rc2 the card is registered again: the
topology loads, and speaker, mics and HDMI outputs are back, with no
warnings in the log.
