Subject: [PATCH] ASoC: SOF: topology: set trigger order for FE DAI link
Git-commit: 5eee2b3f60065a2530d13f28e771be48b989eb4c
Patch-mainline: v5.5-rc1
References: git-fixes

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.
