Commit 0788257aeebe ("hwrng: Explicitly include correct DT includes")
removed an implicit include of io.h. On most architectures, there's
still an implicit include of it, but not on s390. Enabling COMPILE_TEST
in commit 1ce1cd8208ad ("hwrng: Enable COMPILE_TEST for more drivers")
exposed this.

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.
