Dan Carpenter 2646a49e62 net/mlx4: prevent potential use after free in mlx4_en_do_uc_filter()
[ Upstream commit 4f0d91ba72811fd5dd577bcdccd7fed649aae62c ]

Print "entry->mac" before freeing "entry".  The "entry" pointer is
freed with kfree_rcu() so it's unlikely that we would trigger this
in real life, but it's safer to re-order it.

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.
