[PATCH 0/3] ASoC: SOF: get pipeline instance id from pipe_widget->instance_id

[Bard Liao]

Currently we set pipeline instance id = swidget->pipeline_id, but
pipeline_id is from topology and can be any number. In fact, the
number of pipelines is limited. This patch use ida to allocate pipeline
instance id and will be used for pipeline instance id in the IPC
message.

[PATCH 1/3] ASoC: SOF: ipc4-topology: rename sof_ipc4_widget_free_comp

[Bard Liao]

sof_ipc4_widget_free_comp is dedicated to pipeline. Rename it
to sof_ipc4_widget_free_comp_pipeline.

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
