From: Uwe Kleine-König Date: Mon, 9 Oct 2023 15:59:45 +0000 (+0200) Subject: ASoC: SOF: Convert to platform remove callback returning void X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=52fee5c9158000db607d734383fd862969782de5;p=linux.git ASoC: SOF: Convert to platform remove callback returning void 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.
