You've already set this in the dai_link, no need to do it again.
Okay, correct it in next v5.

Please remove noisy prints like this.
Okay, turn it to dev_debug(...)

If any of these assignments is doing anything there's a problem with the
code.
Yes, when probe failed, program will goto this code.

devm_snd_soc_register_card() and you can remove this function entirely.
do you mean that when I take devm_snd_soc_register_card() to register card,
then I do not need unregister card any more(destroy with device) ?

There is no documentation for this binding, binding documentation is
mandatory. Based on the compatible string this looks like it's specific
to the SoC rather than a design for a board - is the whole card part of
the SoC?
It's my fault, cause the dts patch have not CC you, I will correct it in
next v5
Thanks :)
