A platform device's remove callback is only ever called after the probe callback returned success. In the case of kmb_ocs_aes_remove() this means that kmb_ocs_aes_probe() succeeded before and so platform_set_drvdata() was called with a non-zero argument and platform_get_drvdata() returns non-NULL. This prepares making remove callbacks return void.
