From: Allen-KH Cheng <[email protected]>
In SOF OF device, pm_runtime_put_autosuspend() is not
matching any pm_runtime_get_sync().
This is imbalanced for PM runtime.
Also, for consistency we call pm_runtime_mark_last_busy()
before enabling PM runtime.
1. Remove pm_runtime_put_autosuspend() in probe_complete
2. Reorder PM runtime calls int probe_complete

[1/1] ASoC: SOF: Remove pm_runtime_put_autosuspend() for SOF OF device
commit: 475b17b4a875ef31246c6a038ee60d5ca4982ea5
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
