The return value of fn() wasn't used for a long time,
so no need to assign it to a variable, addressing a
W=1 warning.
This seems to be - with patches from others posted to
the list before - the last W=1 warning in arch/um/.
Fixes: 22e2430d60 ("x86, um: convert to saner kernel_execve() semantics")

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 reStructuredText 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.
