I have merged it with 3.6-rc6 and I have got error at compile time. I have fixed this locally with the following patch [1]. Kindly confirm if the patch is correct?
With that Tested on DA850 EVM Tested on Linux-torvalds 3.6-rc6 master branch merged + [1] Tested ASoC module (aplay & arecord for various frequencies)
