ASoC: amd: Allow I2S wake event after ACP is powerd On
has been applied to the asoc tree at

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.

ACP_PME_EN allows wake interrupt to be generated when I2S wake feature is enabled. On turning ACP On, ACP_PME_EN gets cleared. Setting the bit back ensures that wake event can be received when ACP is On.
