   4 Subject: [PATCH] MLK-16224-2: ASoC: dmaengine_pcm: add fifo_num to
   5  snd_dmaengine_dai_dma_data
   6
   7 In order to support multi-fifo sdma script, the audio driver need to send
   8 the fifo number to dma driver through dma_slave_config, and the cpu_dai
   9 driver should config fifo_num for the audio platform driver, then platform
  10 driver can config fifo_num to dma.
  11 So add new variable fifo_num for struct snd_dmaengine_dai_dma_data.
