Sure, I'll write the .get/.put/.info() for this. Here is the preview of it. Do you think the following is good to go? static int rk3036_codec_antipop_info(struct snd_kcontrol *kcontrol, struct snd_ctl_elem_info *uinfo) { uinfo->type = SNDRV_CTL_ELEM_TYPE_BOOLEAN; uinfo->count = 2; uinfo->value.integer.min = 0; uinfo->value.integer.max = 1; return 0; } static int rk3036_codec_antipop_get(struct snd_kcontrol *kcontrol, struct snd_ctl_elem_value *ucontrol) { struct snd_soc_component *component = snd_kcontrol_chip(kcontrol); int val, ret, regval; ret = snd_soc_component_read(component, INNO_R09, ®val); if (ret) return ret; val = ((regval >> INNO_R09_HPL_ANITPOP_SHIFT) & INNO_R09_HP_ANTIPOP_MSK) == INNO_R09_HP_ANTIPOP_ON; ucontrol->value.integer.value[0] = val; val = ((regval >> INNO_R09_HPR_ANITPOP_SHIFT) & INNO_R09_HP_ANTIPOP_MSK) == INNO_R09_HP_ANTIPOP_ON; ucontrol->value.integer.value[1] = val; return 0; } static int rk3036_codec_antipop_put(struct snd_kcontrol *kcontrol, struct snd_ctl_elem_value *ucontrol) { struct snd_soc_component *component = snd_kcontrol_chip(kcontrol); int val, ret, regmsk; val = (ucontrol->value.integer.value[0] ?
