Thanks, Randy.  Even after these changes there are additional kernel
doc warnings.   Missing are the parameter definitions for
restrict_link_by_builtin_trusted() and
restrict_link_by_builtin_and_secondary_trusted().   The first three are
exactly the same as for restrict_link_by_signature().  The fourth parm
needs to be tweaked.
