[ Upstream commit 57b100d4cf14276e0340eecb561005c07c129eb8 ] The cpupower_write_sysfs() function currently returns -1 on write failure, but the function signature indicates it should return an unsigned int. Returning -1 from an unsigned function results in a large positive value rather than indicating an error condition. Fix this by returning 0 on failure, which is more appropriate for an unsigned return type and maintains consistency with typical success/failure semantics where 0 indicates failure and non-zero indicates success (bytes written).

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.
