[PATCH] ASoC: SOF: Intel: add min/max channels for SSP on Baytrail/Broadwell
Major regressions were detected by SOF CI on CherryTrail and Broadwell:
[ 25.705750] SSP2-Codec: ASoC: no backend playback stream [ 27.923378] SSP2-Codec: ASoC: no users playback at close - state
This is root-caused to the introduction of the DAI capability checks with snd_soc_dai_stream_valid(). Its use in soc-pcm.c makes it a requirement for all DAIs to report at least a non-zero min_channels field.
For some reason the SSP structures used for SKL+ did provide this information but legacy platforms didn't.

Applied, thanks!
[1/1] ASoC: SOF: Intel: add min/max channels for SSP on Baytrail/Broadwell commit: 8c05246c0b58cbe80580ea4be05f6d51228af8a9
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
