The patch

   ASoC: SOF: Do not reset hw_params for streams that ignored suspend

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.7

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

Subject: [PATCH] ASoC: SOF: Do not reset hw_params for streams that ignored
 suspend

Setting the prepared flag to false marks the streams for the
hw_params to be reset upon resuming. In the case of
the D0i3-compatible streams that ignored suspend to
keep the pipeline active in the DSP during suspend,
this should not be done.
