After printing the list of thermal governors, then this function prints
a newline character. The problem is that "size" has not been updated
after printing the last governor. This means that it can write one
character (the NUL terminator) beyond the end of the buffer.
Get rid of the "size" variable and just use "PAGE_SIZE - count" directly.

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.
