There are a couple of patches that are ABI changes afaik for PCM
config/capabilities.

Mengdong, can you point us to your latest code for alsa-lib and kernel
with the ABI updates. We can then review the final changes.

Vinod, Subhransu, please shout if there is anything missing from the
final ABI updates in Mengdongs alsa-lib/kernel branches.

Thanks

Liam
