The patch
ASoC: pcm: allow delayed suspending request by users
has been applied to the asoc tree at
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git
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

If a device would like to use delayed suspending then PM recommendation is to set ‘power.use_autosuspend’ flag. To allow users to do so we need to change runtime calls in core to use autosuspend counterparts.
For user who do not wish to use delayed suspend not setting the device's ‘power.use_autosuspend’ flag will result in non-delayed suspend even with these APIs which incidentally is also the default behaviour, so only users will be impacted who opt in for this.
