This all looks good apart from a couple of small things that should be easy to fix:

You should add this to SND_SOC_ALL_CODECS.
Sure, I will add this in next version.

This will report that it handled the interrupt unconditionally, this means that if the interrupt fires in error or there's some bug the interrupt will never be acknowledged (it looks like the chip requires acks?) but the interrupt core won't be able to notice and handle the problem as effectively as it could've done. It's better to report IRQ_NONE if nothing as handled so that the core can do error handling.
I agree, Will fix this in next version!
thanks, srini
