[ Upstream commitca082f019d] strncat() usage in adf7242_debugfs_init() is wrong. The size given to strncat() is the maximum number of bytes that can be written, excluding the trailing NULL. Here, the size that is passed, DNAME_INLINE_LEN, does not take into account the size of "adf7242-" that is already in the array. In order to fix it, use snprintf() instead.

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.
