New Revision: 299213
URL: https://svnweb.freebsd.org/changeset/base/299213
Log:
Clean up callers of nd6_prelist_add().
nd6_prelist_add() sets *newp if and only if it is successful, so there's no
need for code that handles the case where the return value is 0 and
*newp == NULL. Fix some style bugs in nd6_prelist_add() while here.
