| |
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.
