SubjectApplied "ASoC: mediatek: fix error handling in mt2701_afe_pcm_dev_probe()" to the asoc tree
Date
The patch

ASoC: mediatek: fix error handling in mt2701_afe_pcm_dev_probe()

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: mediatek: fix error handling in
mt2701_afe_pcm_dev_probe()

Fix unbalanced error handling path which will get incorrect counts
if probe failed. The .remove() should be adjusted accordingly.
