Thanks!
[1/1] ASoC: msm8916-wcd-digital: Fix missing clk_disable_unprepare() in msm8916_wcd_digital_probe commit: 375a347da4889f64d86e1ab7f4e6702b6e9bf299
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

Hi, I think that the same should be done for 'priv->mclk' if devm_snd_soc_register_component() returns an error.
Can you give it a look?

Hi,
Yes, I agree with you. We should check the error code of devm_snd_soc_register_component() and do corresponding handling.

You already fixed the first issue, do you mind sending a patch for this one as well?
