I faced this problem and thanks to the help of Sebastian Hesselbarth who noticed the possible error located in the structure snd_soc_dapm_route tlv320aic23_intercon[] , now errors are not reported.

Hi,

The patch itself looks good, but the commit message needs some work.

The subject line should be something like "ASoC: tlv320aic23: ..." to 
indicate that this is for the ASoC subsystem and the tlv320aic23 driver.

The commit message should be line-wrapped at around 76 characters.

Signed-off-by and From tag need to have your full name.
