This chip doesn't support asymmetric sample rates.
Is there a method of prohibiting it on ALSA ?
Or should I add any lock ?

This XXX_UNLOCK doesn't mean "disable"..
In default, we can not change value on some register
because it is locked.
So, this driver unlock it here.
Should I add some comment ?
