description:
Set the "required modules" to NULL, not to an empty string.

It really doesn't make that much difference to the code, but the output
from modstat(8) is different!  (With an empty string in the MODULE() macro
modstat reports an empty string, but with a NULL in the macro, modstat
prints a '-' just like it does for other "empty" fields.)
