tcp: md5: hide unused variable
Changing from a memcpy to per-member comparison left the size variable unused: net/ipv4/tcp_ipv4.c: In function 'tcp_md5_do_lookup': net/ipv4/tcp_ipv4.c:910:15: error: unused variable 'size' [-Werror=unused-variable] This does not show up when CONFIG_IPV6 is enabled, but the variable can be removed either way, along with the now unused assignment. Fixes: 6797318e623d ("tcp: md5: add an address prefix for key lookup") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: David S. Miller <davem@davemloft.net>
