I'll drop this patch from my series then and will let someone else handle this driver in 3.11. We can probably live without sound support in 3.10 when running a multiplatform kernel, and it will keep working for exynos-only kernels without the patch. Can you have a look at the other three ASoC patches in the series? I think it would still be useful to merge them.
