SubjectApplied "ASoC: dmaengine: Improve of_node test in dmaengine_pcm_request_chan_of()" to the asoc tree
Date
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.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

Subject: [PATCH] ASoC: dmaengine: Improve of_node test in
dmaengine_pcm_request_chan_of()

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.
