Applied to https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-next Thanks! [1/1] ASoC: mt6359: fix failed to parse DT properties commit: 6835302853169441069e11bc4642300c22009c2e 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

Mt6359 platform device is instantiated by mfd_add_devices(). In the case, dev->of_node is NULL so that mt6359_parse_dt() always fails to parse the desired DT properties. Gets the DT properties via dev->parent->of_node.
