There are two issues in this function.
- We can't drop the refrences on "cpu", "codec" and "platform" before we take the reference. This doesn't cause a problem on the first iteration because those pointers start as NULL so the of_node_put() is a no-op. But on the subsequent iterations, it will lead to a use after free.

[1/1] ASoC: qcom: common: Fix refcounting in qcom_snd_parse_of() commit: 4e59dd249cd513a211e2ecce2cb31f4e29a5ce5b
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
