The patch
ASoC: amd: renaming pcm substream names and bytescount params
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

With in ACP, There are three I2S controllers can be configured. (I2S SP ,I2S MICSP and I2S BT).These controllers can support both playback/capture scenarios. Default enabled i2s controller instance is i2s sp instance.
Renamed stream names and bytescount params as i2ssp. These changes required to distinguish with other I2S controller instance pcm substreams and bytescount params.
