Using snprintf() with a format string from task->comm is a bit
dangerous since the string may be controlled by unprivileged
userspace:
drivers/gpu/drm/xe/xe_devcoredump.c: In function 'devcoredump_snapshot':
drivers/gpu/drm/xe/xe_devcoredump.c:184:9: error: format not a string literal and no format arguments [-Werror=format-security]
184 | snprintf(ss->process_name, sizeof(ss->process_name), process_name);
| ^~~~~~~~
In this case there is no reason for an snprintf(), so use a simpler
string copy.
Fixes: b10d0c5e9df7 ("drm/xe: Add process name to devcoredump")

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 reStructuredText 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.
