Deferred probes shouldn't be a problem.

Link is mapped.

You may ignore these "failures" if you don't have ASRC at all. It's
optional based on the SoC design or platform requirement. Refer to:
Documentation/devicetree/bindings/sound/fsl-asoc-card.txt

But I think the log over here could be less confusing. I may try to
clean it later.

Thanks
