nit: AFAIK, there is no such comment style. But you can move comments to one
line before the method call:
// Request update check without callback and user data.
chromeos::CrosLibrary::Get()->GetUpdateLibrary()->
    RequestUpdateCheck(NULL, NULL);

Should place each NULL parameter on a separate line and use // style comment
