in tlv320aic23_set_bias_level, for the case SND_SOC_BIAS_ON, the comment says "vref/mid, osc on, dac unmute" but the code doesn't clear the corresponding bits, thus when resuming, several bits are not cleared preventing the codec from working.
in tlv320aic23_suspend, clearing the active register is not needed as it will be done by tlv320aic23_set_bias_level, when setting bias to SND_SOC_BIAS_OFF
