[PATCH 1/1] ARM: TLV320AIC23 SoC Audio Codec: Fix errors reported related to input routing signals.

From: dobatog <redacted>

The following patch, based on stable v3.19,  corrects the errors that are reported in the boot trace in reference to the Input Signals of the audio codec TLV320AIC23:

tlv320aic23-codec 1-001a: Control not supported for path LLINEIN -> [NULL] -> Line Input
tlv320aic23-codec 1-001a: ASoC: no dapm match for LLINEIN --> NULL --> Line Input
tlv320aic23-codec 1-001a: ASoC: Failed to add route LLINEIN -> NULL -> Line Input
tlv320aic23-codec 1-001a: Control not supported for path RLINEIN -> [NULL] -> Line Input
tlv320aic23-codec 1-001a: ASoC: no dapm match for RLINEIN --> NULL --> Line Input
tlv320aic23-codec 1-001a: ASoC: Failed to add route RLINEIN -> NULL -> Line Input
tlv320aic23-codec 1-001a: Control not supported for path MICIN -> [NULL] -> Mic Input
tlv320aic23-codec 1-001a: ASoC: no dapm match for MICIN --> NULL --> Mic Input
tlv320aic23-codec 1-001a: ASoC: Failed to add route MICIN -> NULL -> Mic Input

I am trying to set the sound system in a CM-510 (Compulab - SoM) based board with DT, using Simple-Card-Audio and  the TLV320AIC23 audio codec included in the SoM . 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.

Tested on CM-510 (Compulab SoM Board).
