kernel/auditsc.c bug

[Lee Revell]

gcc 4.0.2 complains that state is (not "may be", is) used initialized on
line 607:

605         list_for_each_entry_rcu(e, &audit_filter_list[AUDIT_FILTER_USER], list) {
606                 if (audit_filter_user_rules(cb, &e->rule, &state)) {
607                         if (state == AUDIT_DISABLED)
608                                 ret = 0;
609                         break;
610                 }

AFAICT state will always have been initialized if
audit_filter_user_rules() returns nonzero:

590         switch (rule->action) {
591         case AUDIT_NEVER:    *state = AUDIT_DISABLED;       break;
592         case AUDIT_POSSIBLE: *state = AUDIT_BUILD_CONTEXT;  break;
593         case AUDIT_ALWAYS:   *state = AUDIT_RECORD_CONTEXT; break;
594         }
595         return 1;

Is GCC correct that this is a bug (no default case in the switch
statement)?
