[PATCH] ASoC: soc-generic-dmaengine-pcm: use dmaengine_get_dma_device() for DMA device

[Peng Fan (OSS)]

From: Peng Fan <peng.fan@xxxxxxx>

Replace chan->device->dev with dmaengine_get_dma_device(chan) in
dmaengine_dma_dev() so that DMA buffer allocation and mapping go
through the correct device when the DMA controller has per-channel
IOMMU domains (chan_dma_dev=true).
