SubjectApplied "ASoC: samsung: odroid: fix an use-after-free issue for codec" to the asoc tree
The patch

ASoC: samsung: odroid: fix an use-after-free issue for codec

has been applied to the asoc tree at for-5.3

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.

Subject: [PATCH] ASoC: samsung: odroid: fix an use-after-free issue for codec

The codec variable is still being used after the of_node_put() call,
which may result in use-after-free.
