[1/1] ASoC: SOF: mediatek: add shutdown callback commit: e063330a77edbdc57a142a27a82e51dc1361ab9d 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

If we do not shutdown the peripheral properly at shutdown, the whole system crashes after kexec() on the first io access. Let's implement the appropriate callback.
