Our driver needs ".pointer" method.
However, "struct snd_soc_dai_ops" doesn't have the method.
So, I think "struct snd_soc_dai_ops" cannot be applied to our driver.
Searching other drivers, "blackfin/bf5xx-i2s-pcm.c" uses "struct
snd_soc_ops" not "struct snd_soc_dai_ops".
Let me know your opinion.

Thanks,
