While looking at -Wundef warnings, the #if CONFIG_EEH stood out as a possible candidate to convert to #ifdef CONFIG_EEH. It seems that based on Kconfig dependencies it's not possible to build this file without CONFIG_EEH enabled, but based on upstream discussion, it's not clear yet that CONFIG_EEH should be enabled by default. For now, simply fix the -Wundef warning.

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.
