Missing check in acl_test.c unit test

The Jenkins cppcheck job reports that a variable in acl_test.c is assigned a value that is never used. The code in question is at line 93 and is:

090   result = dns_acl_create(mctx, 1, &notgeoip);
091   ATF_REQUIRE_EQ(result, ISC_R_SUCCESS);
092 
093   result = dns_acl_merge(notgeoip, geoip, ISC_FALSE);
094 #endif
095 
096   ATF_CHECK(dns_acl_isinsecure(any));    /* any; */

It would seem that an ATF_REQUIRE_EQ check is required after the call to dns_acl_merge.
