If SND_ATMEL_SOC_SSC_PDC=y and SND_ATMEL_SOC_SSC_DMA=m,
below errors can be found:
sound/soc/atmel/atmel_ssc_dai.o: In function
`atmel_ssc_set_audio':
atmel_ssc_dai.c:(.text+0x6fe): undefined reference to
`atmel_pcm_dma_platform_register'
make: *** [vmlinux] Error 1
After commit 18291410557f ("ASoC: atmel: enable
SOC_SSC_PDC and SOC_SSC_DMA in Kconfig"), SND_ATMEL_SOC_DMA
and SND_ATMEL_SOC_SSC are selected by SND_ATMEL_SOC_SSC_DMA,
SND_ATMEL_SOC_SSC is also selected by SND_ATMEL_SOC_SSC_PDC,
the results are SND_ATMEL_SOC_DMA=m but SND_ATMEL_SOC_SSC=y,
so the errors happen.
This patch make SND_ATMEL_SOC_SSC select SND_ATMEL_SOC_DMA.
