[PATCH] ASoC: mediatek: Fix missing of_node_put in mt2701_wm8960_machine_probe

[Miaoqian Lin]

This node pointer is returned by of_parse_phandle() with
refcount incremented in this function.
Calling of_node_put() to avoid the refcount leak.

Thanks!

[1/1] ASoC: mediatek: Fix missing of_node_put in mt2701_wm8960_machine_probe
      commit: 05654431a18fe24e5e46a375d98904134628a102

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
