[Bixuan Cui]

The platform_node is returned by of_parse_phandle() should have
of_node_put() before return.

Hi Bixuan,

Thanks for catching that.
I found there are other usages of of_parse_phandle() in the file.
Will you handle them together?
If not, I will prepare a patch to fix them after this patch is merged.

Thanks,
Trevor

Hi,
You can send a v2 patch with your fixes base on my patch. The sign-off-by plus the two of us.

Thanks,

Thanks!

[1/1] ASoC: mediatek: mt8195: Add missing of_node_put()
      commit: b2fc2c92d2fd34d93268f677e514936f50dd6b5c

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
