+ * is done in vidconsole_post_probe()) and we don't know what name they will

+ * probing, and probe the required device.
+ *
+ * @name: stdio device name (e.g. "vidconsole")

+ * @sdevp: Returns stdout device, if found, else NULL
+ * @return 0 if found, -ENOENT if no device found with that name, other -ve
