Replace snprintf() with scnprintf() in show_trace_dev_match() to simplify buffer length handling. The scnprintf() function returns the number of characters actually written (excluding the null terminator), which eliminates the need for manual length checking and clamping. This change removes the redundant size check since scnprintf() guarantees that the return value will never exceed the buffer size, making the code cleaner and less error-prone.

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.
