Please make this very clear in the future.
Hello David, I'm sorry, the patch applies to the linux-next tree. In the future I will be very careful about sending patches that fix problems related to the merging of different trees.

This fixes the sparse warning below about assignment from incompatible pointer type. In the following commit the third argument in function ipv6_chk_addr was changed to const and struct nf_ipv6_ops was introduced with the third argument of .chk_addr beeing const. 2a7851bffb008ff4882eee673da74718997b4265 ("netfilter: add nf_ipv6_ops hook to fix xt_addrtype with IPv6") The below commit introduced the warning as the third argument of dummy_ipv6_chk_addr and .ipv6_chk_addr in struct pingv6_ops is missing a const. 6d0bfe22611602f36617bc7aa2ffa1bbb2f54c67 ("net: ipv6: Add IPv6 support to the ping socket.")
