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)
