ACPICA: Add post-order callback to acpi_walk_namespace
The existing interface only has a pre-order callback. This change adds an additional parameter for a post-order callback which will be more useful for bus scans. ACPICA BZ 779. Also update the external calls to acpi_walk_namespace. http://www.acpica.org/bugzilla/show_bug.cgi?id=779 Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
