br_switchdev_fdb_notify() creates an on-stack FDB info variable, and initializes it member by member. As such, newly added fields which are not initialized by br_switchdev_fdb_notify() will contain junk bytes from the stack. Other uses of struct switchdev_notifier_fdb_info have a struct initializer which should put zeroes in the uninitialized fields. Add a reminder above the structure for future developers. Recently discussed during review.

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.
