Commit 931ca7ab7fe8 ("ip*_mc_gsfget(): lift copyout of struct group_filter into callers") adjusted the type annotations for ip6_mc_msfget() at its declaration, but missed the type annotations at its definition.
Hence, sparse complains on ./net/ipv6/mcast.c:
mcast.c:550:5: error: symbol 'ip6_mc_msfget' redeclared with different type \ (incompatible argument 3 (different address spaces))
Make ip6_mc_msfget() annotations consistent, which also resolves this warning from sparse:
mcast.c:607:34: warning: incorrect type in argument 1 (different address spaces) mcast.c:607:34: expected void [noderef] __user *to mcast.c:607:34: got struct __kernel_sockaddr_storage *p
No functional change. No change in object code.

David, Jakub, please pick this minor non-urgent clean-up patch.
