The ret variable is used to check function return values and assigning values to it on error has no effect as it is an unused value. The current implementation uses an additional variable (fret) to return the error value, which in this case is unnecessary and lead to the above described misuse. There is no restriction in the current implementation to always return -1 on error and the actual negative error value can be returned safely without storing -1 in a specific variable. Simplify the error checking by using a single variable which always holds the returned value.

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.
