[PATCH v7 1/2] cros_ec_commands: Add EC_CODEC_I2S_RX_RESET
Add the new command EC_CODEC_I2S_RX_RESET in ec_codec_i2s_rx_subcmd, which is used for resetting the EC codec.

It is not guaranteed that I2S RX is disabled when the kernel booting. For example, if the kernel crashes while it is enabled, it will keep enabled until the next time EC reboots. Reset I2S RX when probing to fix this issue.

Hi Yu-Hsuan,
Thanks to apply the nit, but you can maintain the reviewed tag.

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
