The patch
ASoC: Intel: Skylake: Create Pipe to widget list in soc probe
has been applied to the asoc tree at
git://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

We need to Identify the DSP pipe type and based on it being a pass thru pipeline or not, we need to copy the pipeline params.
Pipe to widget mapping was earlier done in pre PMD widget handler, but since the pipe type would now be required in hw_params for bypass pipelines we need to move this to be done during the ASoC probe of the platform component.
