ACPICA: Fix to handle NULL package elements correctly
Fixed problem where NULL package elements were not returned to the AcpiEvaluateObject interface correctly. Instead of returning a NULL ACPI_OBJECT package element, the element was simply ignored, potentially causing a buffer overflow and/or confusing the caller who expected a fixed number of elements. http://bugzilla.kernel.org/show_bug.cgi?id=10132 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>
