[PATCH 047/112] ACPI: thinkpad-acpi: add X61t HKEY events

Len Brown

From: Henrique de Moraes Holschuh <hmh@hmh.eng.br>

Tomas Carnecky reports that events 0x5009 and 0x500a are swivel events, and
that 0x500b/0x500c are tablet pen storage bay events.

Document these events, and avoid nasty messages when they happen.
