Commit 061981ff8cc8 ("ASoC: atmel: properly select dma driver state") changed the way that the dependencies are handled, but then the Class D amplifier support got merged, which used the old method.
This seems to have triggered a very rare randconfig condition for me now, leading to a link error:

Changing it to select SND_ATMEL_SOC_SSC_DMA as intended rather than SND_ATMEL_SOC_DMA directly makes it work again.

Unfortunately, my testing just found a new problem with this patch applied, I had not run enough randconfig tests on top of it:
sound/soc/atmel/atmel_ssc_dai.o: In function `atmel_ssc_set_audio': atmel_ssc_dai.c:(.text+0x73c): undefined reference to `ssc_request' sound/soc/atmel/atmel_ssc_dai.o: In function `atmel_ssc_put_audio': atmel_ssc_dai.c:(.text+0x7be): undefined reference to `ssc_free'
This is for a configuration with SND_ATMEL_SOC_CLASSD=y and CONFIG_ATMEL_SSC=n. Could you tell me whether that is a sensible configuration that should work, or whether we need a dependency on ATMEL_SSC in SND_ATMEL_SOC_CLASSD? I can't really tell from the source code, but you probably know the answer.
