Hi Mark,
Sorry again. You suggest to create a new structure for these entries,
for example:

/* Out Bypass mixer switch */
static const struct snd_kcontrol_new max98088_out_bypass_mixer_controls[] = {
       SOC_DAPM_SINGLE("INA Switch", M98088_REG_4A_CFG_BYPASS, 7, 1, 0),
       SOC_DAPM_SINGLE("MIC2 Switch", M98088_REG_4A_CFG_BYPASS, 4, 1, 0),
       SOC_DAPM_SINGLE("REC Switch", M98088_REG_4A_CFG_BYPASS, 1, 1, 0),
       SOC_DAPM_SINGLE("SPK Switch", M98088_REG_4A_CFG_BYPASS, 0, 1, 0),
};

Let me know.

Thanks in advance.
Tommaso
