The function returns zero unconditionally. Change it to return void instead which simplifies some callers as error handing becomes unnecessary. The function is also used for some drivers as remove callback. Switch these to the .remove_new() callback. For some others no error can happen in the remove callback now, convert them to .remove_new(), too.
