Oh dear, you killed Schrödinger's cat..

Yes there are some bugs in the s6000 ASoC code.
A missing semicolon at the end of s6000_i2s_dai, a lacking forward
declaration of s6000_soc_platform in the request_irq line, and a reference
to codec->snd_card which should probably be changed to codec->card->snd_card.

But trying to build a s6105 kernel from vanilla sources made me realize
two things:
1. Nobody ever tried to do that before as s6000 support has been merged
   incompletely and in some cases with merge errors (variant_irq_disable
   declaration, I2C_BOARD_INFO in struct platform_device[], clk framework
   missing completely).
2. Compiling Xtensa kernels in general is broken at least since 2.6.35-rc1
   because of e520c41085

So for now I could just compile-test the ASoC changes. Actually booting a
kernel will probably take more of my spare time..
Would you like to have patches for the found ASoC bugs now or do you prefer
waiting until I could make it work on hardware?
