Martin Preuss 17d4ce5125 Change AQH_Value field NameForDriver to Name and make it only contain the value name.
Previously this field contained the device name, too. This would make it
necessary for drivers to remove the device part of the name when SetValue
is called. Instead the device name is now always provided by the driver in
the appropriate field DeviceNameForDriver.
