What makes you claim this - *why* does your DAI driver need a pointer
method?

Of course the DMA driver uses the ops for DMA drivers!  Alternatively if
your question above is about your DMA driver then why is your DMA driver
using DAI ops?

To repeat what I said above in a different way *please* put more effort
into understanding things and trying to solve problems for yourself, or
improving the way you ask questions.
