SubjectApplied "ASoC: core: allow a dt node to provide several components" to the asoc tree
The patch

ASoC: core: allow a dt node to provide several components

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: core: allow a dt node to provide several components

At the moment, querying the dai_name will stop of the first component
matching the dt node. This does not allow a device (single dt node) to
provide several ASoC components which could then be used through DT.

This change let the search go on if the xlate function of the component
returns an error, giving the possibility to another component to match
and return the dai_name.
