Hi,
I just found that after commit be3ea3b9e
"SoC: Use new register map API for ASoC generic physical I/O",
snd_soc_codec_set_cache_io does not set codec->hw_write any more.

It is still used in some drivers. e.g.
In wm8988_resume, we call codec->hw_write(codec->control_data, data, 2);

For the drivers that is using snd_soc_codec_set_cache_io now,
where is the place to set codec->hw_write callback now? 

Regards,
Axel
