alsa-project/alsa-utils pull request #248 was opened from andyross:
This partially reverts commit 3a47ef2487ed ("topology: nhlt: intel: support more device types and directions"), which changed the default device_type in the endpoint descriptor from zero to SSP_ANALOG.
This change breaks the Linux kernel NHLT parser (which AFAICT doesn't recognize SSP_ANALOG at all), producing errors like:

Revert for compatibility.
