[1/1] ALSA: SOF: sof-pci-dev: Fix community key quirk detection commit: 7dd692217b861a8292ff8ac2c9d4458538fd6b96 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

[PATCH] ASoC: SOF: Convert to platform remove callback returning void
by Uwe Kleine-König 10 Oct '23

10 Oct '23

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). The SOF platform drivers all use either sof_of_remove() or sof_acpi_remove() which both return zero unconditionally. Change these functions to return void and the drivers to use .remove_new(). There is no semantical change.
