bridge: Convert compare_ether_addr to ether_addr_equal
Use the new bool function ether_addr_equal to add some clarity and reduce the likelihood for misuse of compare_ether_addr for sorting. Done via cocci script: $ cat compare_ether_addr.cocci @@ expression a,b; @@ - !compare_ether_addr(a, b) + ether_addr_equal(a, b) @@ expression a,b; @@ - compare_ether_addr(a, b) + !ether_addr_equal(a, b) @@ expression a,b; @@ - !ether_addr_equal(a, b) == 0 + ether_addr_equal(a, b) @@ expression a,b; @@ - !ether_addr_equal(a, b) != 0 + !ether_addr_equal(a, b) @@ expression a,b; @@ - ether_addr_equal(a, b) == 0 + !ether_addr_equal(a, b) @@ expression a,b; @@ - ether_addr_equal(a, b) != 0 + ether_addr_equal(a, b) @@ expression a,b; @@ - !!ether_addr_equal(a, b) + ether_addr_equal(a, b) Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S.
