Hi Willem,

Thank you for the patch! Perhaps something to improve:

[auto build test WARNING on net-next/master]

url:    https://github.com/0day-ci/linux/commits/Willem-de-Bruijn/icmp6-support-rfc-4884/20200723-223533
base:   https://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next.git 7fc3b978a8971305d456b32d3f2ac13191f5a0d7
config: i386-randconfig-s001-20200723 (attached as .config)
compiler: gcc-9 (Debian 9.3.0-14) 9.3.0
reproduce:
        # apt-get install sparse
        # sparse version: v0.6.2-93-g4c6cbe55-dirty
        # save the attached .config to linux build tree
        make W=1 C=1 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__' ARCH=i386 

If you fix the issue, kindly add following tag as appropriate
Reported-by: kernel test robot <lkp@...el.com>


sparse warnings: (new ones prefixed by >>)

>> net/ipv6/datagram.c:288:6: sparse: sparse: symbol 'ipv6_icmp_error_rfc4884' was not declared. Should it be static?

Please review and possibly fold the followup patch.
