[PATCH] ASoC: fsl_asrc_dma: request dma channel from specific controller

[Shengjiu Wang]

From: Robin Gong <yibin.gong@xxxxxxx>

Request dma channel from specific dma controller instead of generic
dma controller list, otherwise, may get the wrong dma controller
if there are multi dma controllers such as i.MX8MP.
