[PATCH 1/6] dt-bindings: sound: Convert jz4740-i2s doc to YAML
Convert the textual binding documentation for the AIC (AC97/I2S Controller) of Ingenic SoCs to a YAML schema, and add the new compatible strings in the process.

Make the code cleaner by using a "struct device *dev" variable instead of dereferencing it everytime from within the struct platform_device.

The patch
ASoC: jz4740-i2s: Add local dev variable in probe function
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

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.

Cleanup and new development patches like this should always come after any fixes to ensure that there are no dependencies which would prevent fixes being merged as such.
