The patch
ASoC: SOF: topology: set trigger order for FE DAI link
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.5
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.

Set trigger order for FE DAI links to SND_SOC_DPCM_TRIGGER_POST to trigger the BE DAI's before the FE DAI's. This prevents the xruns seen on playback pipelines using the link DMA.
