[1/1] ASoC: SOF: Fix potential NULL pointer dereference commit: 2fe08216fda33bbc1f80133b8fd560ffd094b987 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

Cleanup path for sof_prepare_widgets_in_path() should check if unprepare callback exists before calling it, instead it checks if it does not exist. Fix the check.
