    mlx5: avoid unused variable warning · e6790fd8
    Arnd Bergmann authored
    When CONFIG_NET_CLS_ACT is disabled, we get a new warning in the mlx5
    ethernet driver because the tc_for_each_action() loop never references
    the iterator:
    
    mellanox/mlx5/core/en_tc.c: In function 'mlx5e_stats_flower':
    mellanox/mlx5/core/en_tc.c:431:20: error: unused variable 'a' [-Werror=unused-variable]
      struct tc_action *a;
    
    This changes the dummy tc_for_each_action() macro by adding a
    cast to void, letting the compiler know that the variable is
    intentionally declared but not used here. I could not come up
    with a nicer workaround, but this seems to do the trick.
