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 the DSP is in low power mode, it needs to be woken up by a "wake" IPC to set it into the D0 state before we can send any other IPC command.
The call flow is that the driver calls sst_ipc_tx_message_wait() to send any IPC and this call checks if the device is in low power mode and in that case we need to send the wake IPC.
So add a new IPC nopm variant which can be called from driver and doesn't check for power state (as we already know that) and avoids circular dependency of again checking power state.
