Global variables: I'm afraid yes. They should be accessible to test cases
(e.g. drivers/platform/chrome/cros_ec_proto_test.c).

Exported: I'm not sure if I fixed it in a proper way. They were added for
fixing https://lkml.org/lkml/2022/6/2/452. When CONFIG_CROS_KUNIT=m and
CONFIG_CROS_EC_PROTO_KUNIT_TEST=m, cros_ec_proto_test.c still needs to access
them (in cros_kunit_util.c).
