static ssize_t smu_v13_0_6_get_ecc_info(struct smu_context *smu,
                        void *table)
 {
-       /* Support ecc info by default */
-       return 0;
+       /* we use debug mode flag instead of this interface */
+       return -EOPNOTSUPP;
 }

Shall we just drop the callback implementation? smu_get_ecc_info will return -EOPNOTSUPP if the callback is not supported.

Regards,
Hawking
