The patch
ASoC: atmel: tse850: rely on the ssc to register as a cpu dai by itself
has been applied to the asoc tree at
git://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

This breaks devicetree compatibility, but in this case that is ok. All affected units are either on my desk, or running an even older version of the driver that is not compatible with the upstreamed version anyway (and when these other units are eventually updated, they will get a fresh dtb as well, so that is not a significant problem either).
All of that is of course assuming that noone else has managed to build something that can use this driver, but that seems extremely improbable.
