[1/2] ASoC: fsl_mqs: move of_node_put() to the correct location commit: 1c34890273a020d61d6127ade3f68ed1cb21c16a 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

of_node_put() should have been done directly after mqs_priv->regmap = syscon_node_to_regmap(gpr_np); otherwise it creates a reference leak on the success path. To fix this, of_node_put() is moved to the correct location, and change all the gotos to direct returns.
