[1/1] ASoC: imx-audmix: Add NULL check in imx_audmix_probe commit: e038f43edaf0083f6aa7c9415d86cf28dfd152f9 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

devm_kasprintf() can return a NULL pointer on failure,but this returned value in imx_audmix_probe() is not checked. Add NULL check in imx_audmix_probe(), to handle kernel NULL pointer dereference error.
