thinkpad-acpi: drop HKEY event 0x5010
HKEY event 0x5010 is useless to us: old ThinkPads don't issue it. Newer ThinkPads won't issue it anymore. And all ThinkPads issue 0x1010 and 0x1011 events. Just silently drop it instead of sending it to userspace. Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Signed-off-by: Len Brown <len.brown@intel.com>
