-Subject: [PATCH] MLK-16224-2: ASoC: dmaengine_pcm: add fifo_num to
- snd_dmaengine_dai_dma_data
-
-In order to support multi-fifo sdma script, the audio driver need to send
-the fifo number to dma driver through dma_slave_config, and the cpu_dai
-driver should config fifo_num for the audio platform driver, then platform
-driver can config fifo_num to dma.
-So add new variable fifo_num for struct snd_dmaengine_dai_dma_data.
