[ Upstream commit 3690c8c9a8 ]
strncpy() does not ensure NULL-termination when the input string
size equals to the destination buffer size 30.
The output string is passed to qed_int_deassertion_aeu_bit()
which calls DP_INFO() and relies NULL-termination.
Use strlcpy instead. The other conditional branch above strncpy()
needs no fix as snprintf() ensures NULL-termination.
This issue is identified by a Coccinelle script.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
