[PATCH 0/8] ASoC: SOF: trivial code/log/comment improvements

Pierre-Louis Bossart (4): ASoC: SOF: IPC: reduce verbosity of IPC pointer updates ASoC: SOF: acpi: add dev_dbg() log for probe completion ASoC: SOF: Intel: add dev_dbg log when driver is not selected ASoC: Intel: use consistent HDAudio spelling in comments/docs
Ranjani Sridharan (2): ASoC: SOF: topology: remove unnecessary memory alloc for sdev->private ASoC: SOF: topology: reduce the log level for unhandled widgets

Several fields in struct snd_sof_dev are used as boolean flags, use the "bool" type for them.

Looks like it was left over from the previous implementation of DMIC PDM token parsing. It is not used anymore.

Virtual widgets are added to topology to be compatible with legacy machine drivers. Reduce the log level for messages printed when such widgets are ignored by the SOF driver.

When using dynamic debug, the console is swamped with verbose position pointer logs, which really don't add much information. Move then to vdbg to keep traces usable and allow for easier end-user support.

When the probe relies on a workqueue, the completion is not signaled by a return value. Mirror the log already present for PCI probe, so that CI checks can test if the probe actually worked by filtering the console logs.

Mirror change suggested in legacy HDaudio driver.
On SKL+ Intel platforms, the driver selection is handled by the snd_intel_dspcfg, and when the HDaudio legacy driver is not selected, be it with the auto-selection or user preferences with a kernel parameter, the probe aborts with no logs, only a -ENODEV return value.
Having no dmesg trace, even with dynamic debug enabled, makes support more complicated than it needs to be, and even experienced users can be fooled. A simple dev_dbg() trace solves this problem.

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
