In the current code, we enable a widget core when it is set up and disable it when it is freed. This is problematic with IPC4 because widget free is essentially a NOP and all widgets are freed in the firmware when the pipeline is deleted. This results in a crash during pipeline deletion when one of it's widgets is scheduled to run on a secondary core and is powered off when widget is freed. So, change the logic to enable all cores needed by all the modules in a pipeline when the pipeline widget is set up and disable them after the pipeline widget is freed.

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
