static int ak4535_probe(struct snd_soc_codec *codec) {
- struct ak4535_priv *ak4535 = snd_soc_codec_get_drvdata(codec);
- int ret;
- codec->control_data = ak4535->regmap;
- ret = snd_soc_codec_set_cache_io(codec, 8, 8, SND_SOC_REGMAP);

Are you sure that the set_bias_level() call doesn't do anything with I/O? Can I suggest sending a patch that just does the drivers that only do set_cache_io() and nothing else in probe - that would be really quick and simple to fix.
- ret = snd_soc_codec_set_cache_io(codec, 8, 8, SND_SOC_REGMAP);
- if (ret < 0) {
dev_err(codec->dev, "Failed to set cache I/O: %d\n", ret);return ret;- }
- /* Default to using ALC auto offset calibration mode. */ snd_soc_update_bits(codec, DA7213_ALC_CTRL1, DA7213_ALC_CALIB_MODE_MAN, 0);
This one will fail.
Sorry, I'm not very understand why will this fail ? Before the ASoC probe, the ASoC core will set the I/O. :)
