The earlier acp_reset flag is set to true in two instances as mentioned below. 1. When active SoundWire manager instances power mode is set to Power off mode when SoundWire configuration is selected. 2. For other acp configurations
As code being refactored and common function being used for scanning SoundWire controller, acp_reset flag update logic is dropped.
Instead of it, check the SoundWire manager instance enable state, based on it update sdw_en_stat flag which will be used to apply ACP init/de-init sequence during suspend/resume callbacks based on flag set value when SoundWire configuration is selected. For other acp configurations, acp init/de-init will be called by default.
Refactor existing pm ops logic for SoundWire configuration and use sdw_en_stat flag for invoking acp init/de-init sequence.

Consider the below scenario, When ACP and SoundWire managers are in D3 state and SoundWire manager power off mode is selected and acp and SoundWire manager instances are in runtime suspended state.
In this case, for the ACP PME wake event, the ACP PCI driver should resume SoundWire manager devices based on wake enable status set.
Add code for handling ACP PME wake event for runtime suspend scenario when SoundWire power off mode is selected.

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.
