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. Make simatic_ipc_leds_gpio_remove() return void instead of returning zero unconditionally. After that the three remove callbacks that use this function were trivial to convert to return void, too.
