Re: [alsa-devel] [PATCH next] ASoC: atmel: fix build error with CONFIG_SND_ATMEL_SOC_DMA=m

If CONFIG_SND_ATMEL_SOC_DMA=m, build error:

sound/soc/atmel/atmel_ssc_dai.o: In function `atmel_ssc_set_audio': (.text+0x7cd): undefined reference to `atmel_pcm_dma_platform_register'

Function atmel_pcm_dma_platform_register is defined under CONFIG SND_ATMEL_SOC_DMA, so select SND_ATMEL_SOC_DMA in CONFIG SND_ATMEL_SOC_SSC, same to CONFIG_SND_ATMEL_SOC_PDC.

Arnd sent a more complete patch for this issue: https://lkml.org/lkml/2019/10/1/620

It wasn't merged due to some integration issues. Could you please try it and let us know if it fixes your issue?

Thanks and best regards, Codrin
