net/ipv4/ping.c:370:6: sparse: symbol 'ping_clear_saddr' was not declared. Should it be static?

net/ipv6/ping.c:60:5: sparse: symbol 'dummy_ipv6_recv_error' was not declared. Should it be static?
net/ipv6/ping.c:64:5: sparse: symbol 'dummy_ip6_datagram_recv_ctl' was not declared. Should it be static?
net/ipv6/ping.c:69:5: sparse: symbol 'dummy_icmpv6_err_convert' was not declared. Should it be static?
net/ipv6/ping.c:73:6: sparse: symbol 'dummy_ipv6_icmp_error' was not declared. Should it be static?
net/ipv6/ping.c:75:5: sparse: symbol 'dummy_ipv6_chk_addr' was not declared. Should it be static?
net/ipv6/ping.c:201:5: sparse: symbol 'ping_v6_seq_show' was not declared. Should it be static?
