thinkpad-acpi: Fix procfs hotkey reset command
echo "reset" > /proc/acpi/ibm/hotkey should do something non-useless, so instead of setting it to Fn+F2, Fn+F3, Fn+F5, set it to hotkey_recommended_mask. It is not like it will survive for much longer, anyway. Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Signed-off-by: Len Brown <len.brown@intel.com>
