[ Upstream commit719fdd3292] The cell name stored in the afs_cell struct is a 64-char + NUL buffer - when it needs to be able to handle up to AFS_MAXCELLNAME (256 chars) + NUL. Fix this by changing the array to a pointer and allocating the string. Found using Coverity.

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.
