Please use a C++ comment for the whole block to make things look more
consistent.
okay, I will follow C++ comment.

AFAICT this will only work well if max is 1, just hard code that.
You are right, I will modify to hard code for the max is 1.

Please use mixer-test to verify that your controls conform to the
expected API, the return value here is not what's expected - it should
be a negative value for an error, 0 for no change and 1 for change.
I think the return value is always 0 and 1, and I will modify the return value for zero.

Shouldn't this be a Switch?
Yes, you are right. I will change it.
+ SOC_SINGLE("ALC Enable", NAU8325_R2E_ALC_CTRL3,

ALC Switch.
okay, I will correct the name to "ALC Enable Switch".

What happens if someone enables clock detection while things are powered
up?
This clock detection switch usually does not turn on/off during execution. If this is the case,
there is a chance that unexpected exceptions may occur. So we'll remove the "Clock Detection" switch. The
mode is determined during the initialization phase.
