This doesn't apply against current code, please check and resend.

Hi, Mark

Thank you for your reply,
This patch depends on Cheng-Yi's patch series
https://patchwork.kernel.org/patch/11773221/.

If I misunderstand what you mean, please correct me,
Thank you,

That's "ASoC: qcom: dt-bindings: Add sc7180 machine bindings" for those
playing at home.

> If I misunderstand what you mean, please correct me,

A version of some SC7180 patches was applied. However it does seem like
that didn't include any machine driver bindings so it must've been a
different, similar looking series which is presumably waiting for a new
version - please resend based on that new version (ideally these patches
could be picked up as part of that series).

Please include human readable descriptions of things like commits and
issues being discussed in e-mail in your mails, this makes them much
easier for humans to read especially when they have no internet access.
I do frequently catch up on my mail on flights or while otherwise
travelling so this is even more pressing for me than just being about
making things a bit easier to read.

Thanks!

(no commit info)
[2/2] ASoC: qcom: sc7180: Modify machine driver for 2mic
commit: 3cfbf07c6d2779d24a6f5b999a91f400256b1d4e

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
