From: Uwe Kleine-König Date: Fri, 13 Oct 2023 22:19:51 +0000 (+0200) Subject: ASoC: meson: Make meson_card_remove() return void X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=8210f496c3e12410fa240c7fbc63f71ef78e253f;p=linux.git ASoC: meson: Make meson_card_remove() return 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 (mostly) ignored 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. meson_card_remove() returned zero unconditionally. Make it return void instead and convert all users to struct platform_device::remove_new().
