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. simple_util_remove() returned zero unconditionally. Make it return void instead and convert all users to struct platform_device::remove_new().
