[PATCH] ASoC: mt6797-mt6351: Fix refcount leak in mt6797_mt6351_dev_probe
of_parse_phandle() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. Add missing of_node_put() to avoid refcount leak.

[1/1] ASoC: mt6797-mt6351: Fix refcount leak in mt6797_mt6351_dev_probe commit: 7472eb8d7dd12b6b9b1a4f4527719cc9c7f5965f
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
