Commit ac950278b087 ("ASoC: add N cpus to M codecs dai link support") added an additional local params in __soc_pcm_hw_params, for the CPU side of the DAI. The snd_pcm_hw_params struct is pretty large (604 bytes) and keeping two local copies of it can make the stack frame really large.
It is worth noting the variables are in separate code blocks so for some optimisation levels in the compiler these will get automatically combined keeping the stack frame reasonable. But better to manually combine them to cover all cases.

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
