[PATCH][V2][next] ASoC: rk817: remove redundant assignment to pointer node, add missing of_node_put
From: Colin Ian King colin.king@canonical.com
The pointer node is being initialized with a value that is never read and it is being updated later with a new value. The initialization is redundant and can be removed.
The function is missing a of_node_put on node, fix this by adding the call before returning.

Tested these changes and they appear to work just fine. Thank you.

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
