Subject[PATCH AUTOSEL 5.4 292/459] ASoC: atmel: fix build error with CONFIG_SND_ATMEL_SOC_DMA=m
Date
From: Chen Zhou <chenzhou10@huawei.com>

[ Upstream commit 8fea78029f5e6ed734ae1957bef23cfda1af4354 ]

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.
