    Subject[PATCH 01/22] ASoC: dmaengine: Improve of_node test in dmaengine_pcm_request_chan_of()
    Date
    Currently when of_node of the "PCM" device is null
    dmaengine_pcm_request_chan_of() function will bail out, including cases
    when custom DMA device is intended to be used. To have the channels
    properly requested when custom DMA device is provided extend the of_node
    test to also consider dma_dev->of_node.
