This construct is usually used to avoid unused variable warnings, which
I assume is the case here. -Wunused-parameter is hidden behind -Wextra
with GCC 4.6, which is the minimum version to compile the kernel as of
commit cafa0010cd51 ("Raise the minimum required gcc version to 4.6").
However, upon further inspection, these functions aren't actually used
anywhere; they're just defined. Rather than just removing the self
assignments, remove all of this dead code.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
