Kees Cook 780f6a9afe lib: zstd: Fix -Wstringop-overflow warning
Fix the following -Wstringop-overflow warning when building with GCC 11+:

lib/zstd/decompress/huf_decompress.c: In function ‘HUF_readDTableX2_wksp’:
lib/zstd/decompress/huf_decompress.c:700:5: warning: ‘HUF_fillDTableX2.constprop’ accessing 624 bytes in a region of size 52 [-Wstringop-overflow=]

by using pointer notation instead of array notation.

This is one of the last remaining warnings to be fixed before globally
enabling -Wstringop-overflow.

README

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.
