 * FUNCTION:    acpi_ex_do_debug_object
 *
 * PARAMETERS:  source_desc         - Object to be output to "Debug Object"
 *              level               - Indentation level (used for packages)
 *              index               - Current package element, zero if not pkg
 *
 * RETURN:      None
 *
 * DESCRIPTION: Handles stores to the AML Debug Object. For example:
 *              Store(INT1, Debug)
 *
 * This function is not compiled if ACPI_NO_ERROR_MESSAGES is set.
 *
 * This function is only enabled if acpi_gbl_enable_aml_debug_object is set, or
 * if ACPI_LV_DEBUG_OBJECT is set in the acpi_dbg_level. Thus, in the normal
 * operational case, stores to the debug object are ignored but can be easily
 * enabled if necessary.
