The patch

ASoC: core: Allow soc_find_component lookups to match parent of_node

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

For devices implemented as a MFD it is common to only have a single node in devicetree representing the whole device. As such when looking up components in soc_find_components we should match against both the devices of_node and the devices parent's of_node, as is already done in the rest of the ASoC core.

This causes regressions for some DAI links at the moment as soc_find_component was recently added as a check in soc_init_dai_link.
