In order to pass functions to kunit_add_action(), they need to be of the kunit_action_t type. While casting the function pointer can work, it will break control-flow integrity. drm_kunit_helpers already defines wrappers, but we now have a macro which does this automatically. Using this greatly reduces the boilerplate needed.
