[ Upstream commit 8e28276a569addb8a2324439ae473848ee52b056 ]
The static initializer for struct watchdog_info::identity is too long
and gets initialized without a trailing NUL byte. Since the length
of "identity" is part of UAPI and tied to ioctls, just shorten
the name of the device. Avoids the warning seen with GCC 15's
-Wunterminated-string-initialization option:
drivers/watchdog/exar_wdt.c:224:27: warning: initializer-string for array of 'unsigned char' truncates NUL terminator but destination lacks 'nonstring' attribute (33 chars into 32 available) [-Wunterminated-string-initialization]
224 | .identity = "Exar/MaxLinear XR28V38x Watchdog",

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.
