ACPI: export ACPI events via acpi_mc_group multicast group
This is an incremental patch for the recent genetlink multicast changes. Now ACPI events are exported via generic netlink multicast group. Thanks for Johannes' help on developing this patch Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
