The changes->changed field indicates which attributes of the device
specified in changes->device have changed. The parameters describing
the changes are contained in the other fields of changes.
XkbGetDeviceInfoChanges uses that information to call
XkbGetDeviceInfo to obtain the current status of those attributes that
have changed. It then updates the local description of the device in
device_info with the new information.
