The patch
ASoC: dmaengine: Improve of_node test in dmaengine_pcm_request_chan_of()
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git
All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.

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.
