[PATCH 0/2] ASoC: SOF: simplify probe and report errors
These patches simplify the sof_probe_complete handling and address reporting of errors during probe.

Two error cases in snd_sof_device_probe() and sof_probe_continue() are missing error prints. If either of them happens it is not possible to identify the reason for the failure.
Add dev_err() prints for the cases to aim debugging.

Set the sof_data->sof_probe_complete callback unconditionally of CONFIG_SND_SOC_SOF_PROBE_WORK_QUEUE.
The sof_probe_complete will be called when the sof_probe_continue() function is successfully executed, called either directly from snd_sof_device_probe() or from the scheduled work.
Since all error cases within the call chain of snd_sof_device_probe() have error prints, there is no need to print again in the acpi/pci/of level.

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
