Say Y if you want to add support for SoC audio on 5912 OSK.
This is generated against linux-omap. Generate it against a tree used in alsa-devel (ASoC dev or Takashi's) since this ASoC for OSK5912 can go directly there. Overo and Beagle are stalled until remaining McBSP updates, OMAP3 and TWL4030 related patches are upstream from linux-omap.

Use this definition also above.

aic23_mclk is not released in this error path so set the err variable and do goto err1 instead of returning.
