Attempt to write various invalid values for control types we know about and check that something sensible happens. The ABI isn't quite as clearly defined as one might like, rather than generating an error when an invalid value is written many devices will silently rewrite the value into one that is valid for the control. The exact value chosen is not predictable so in the case the write succeeds we just check that the value we read back is one that is valid for the control.

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.
