+static void ufs_mtk_init_reset_control(struct ufs_hba *hba,

How about verifying that the line is not shared as well?
Although this might not be an issue on your current platforms,
it might save you aggravation in the future..

+               dev_info(hba->dev, "Failed to get reset control %s: %d\n",
+                        str, PTR_ERR(*rc));
+               *rc = NULL;
+       }
