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(). In the error path emit an error message replacing the (less useful) message by the core. Apart from the improved error message there is no change in behaviour. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.
