ACPICA: Implemented full support for deferred execution for the TermArg string arguments for DataTableRegion
This enables forward references and full operand resolution for the three string arguments. Similar to OperationRegion deferred argument execution.) http://www.acpica.org/bugzilla/show_bug.cgi?id=430 Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Alexey Starikovskiy <astarikovskiy@suse.de> Signed-off-by: Len Brown <len.brown@intel.com>
