* FUNCTION: acpi_rs_create_aml_resources

- * PARAMETERS: linked_list_buffer - Pointer to the resource linked list
- * output_buffer - Pointer to the user's 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
* to the size buffer needed.

- * creates a bytestream to be used as input for the
