  * FUNCTION:    acpi_rs_create_aml_resources

- * PARAMETERS:  linked_list_buffer      - Pointer to the resource linked list
- *              output_buffer           - Pointer to the user's buffer
+ * PARAMETERS:  resource_list           - Pointer to the resource list buffer
+ *              output_buffer           - Where the AML buffer is returned

  * RETURN:      Status  AE_OK if okay, else a valid acpi_status code.
  *              If the output_buffer is too small, the error will be
  *              AE_BUFFER_OVERFLOW and output_buffer->Length will point
