Sysfs "show" methods should return the number of bytes printed into the buffer. This is the return value of scnprintf() [1]. snprintf(buf, size, ...) prints at most "size" bytes into "buf", but returns the number of bytes that *would* be printed if "buf" were large enough. Replace use of snprintf() with scnprintf(). No functional change intended.

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.
