This fixes a possible UAF in if_nlmsg_size(),
which can run without RTNL.
Add rcu protection to "struct dpll_pin"
Move netdev_dpll_pin() from netdevice.h to dpll.h to
decrease name pollution.
Note: This looks possible to no longer acquire RTNL in
netdev_dpll_pin_assign() later in net-next.
v2: do not force rcu_read_lock() in rtnl_dpll_pin_size() (Jiri Pirko)
Fixes: 5f18426928 ("netdev: expose DPLL pin handle for netdevice")

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.
