The two new variables are only used inside of an #ifdef and cause harmless warnings when that is disabled:
drivers/net/ethernet/chelsio/cxgb4/cxgb4_main.c: In function 'init_one': drivers/net/ethernet/chelsio/cxgb4/cxgb4_main.c:4646:9: error: unused variable 'port_vec' [-Werror=unused-variable] drivers/net/ethernet/chelsio/cxgb4/cxgb4_main.c:4646:6: error: unused variable 'v' [-Werror=unused-variable] This adds another #ifdef around the declarations.
