Merge git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf
Pablo Neira Ayuso says:
====================
Netfilter fixes for net
1) Fix cgroupv2 from the input path, from Florian Westphal.
2) Fix incorrect return value of nft_parse_register(), from Antoine Tenart.
* git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf:
netfilter: nf_tables: nft_parse_register can return a negative value
netfilter: nft_socket: make cgroup match work in input too
