Commit 931ca7ab7f ("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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
