[PATCH] ASoC: Intel: broadwell: Fix oops during module removal
When removing the SOF module, the RT286 jack detect handler will oops if jack detection is not disabled. Disable the jack in the machine driver remove callback to prevent this. This fix is only for SOF support and is not needed for earlier versions.

[1/1] ASoC: Intel: broadwell: Fix oops during module removal commit: 8382f2949a0def8e9519603b77b3c26f81a66576
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
