Dominik Czarnota f3cc008bf6 sxgbe: Fix off by one in samsung driver strncpy size arg
This patch fixes an off-by-one error in strncpy size argument in
drivers/net/ethernet/samsung/sxgbe/sxgbe_main.c. The issue is that in:

        strncmp(opt, "eee_timer:", 6)

the passed string literal: "eee_timer:" has 10 bytes (without the NULL
byte) and the passed size argument is 6. As a result, the logic will
also accept other, malformed strings, e.g. "eee_tiXXX:".

This bug doesn't seem to have any security impact since its present in
module's cmdline parsing 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.
