The issue is that SND_ATMEL_SOC_SSC needs ATMEL_SSC to pass compilation.
We now got the build warnings as Stephen points out.
So I revert the patch.
Both SND_AT91_SOC_SAM9G20_WM8731 and SND_AT91_SOC_AFEB9260 selects

I think this patch reverts the problematic patch.
And then you can apply [PATCH] ASoC: Fix build dependency for
