While replacing strncpy() with strscpy(), Bart Van Assche pointed out that the code occurs inside sysfs write callbacks, which already uses NUL-terminated strings. This allows the string to be passed directly to sscanf() without requiring a temporary copy. Remove the deprecated and unnecessary strncpy() and the corresponding local variables, and pass the buffer buf directly to sscanf(). Replace sscanf() with kstrtoint() to silence checkpatch warnings. Compile-tested only.

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.
