When CONFIG_PNP is disabled, the mchbar_addr variable is only written but
not read:
drivers/gpu/drm/i915/soc/intel_gmch.c: In function 'intel_alloc_mchbar_resource':
drivers/gpu/drm/i915/soc/intel_gmch.c:41:13: error: variable 'mchbar_addr' set but not used [-Werror=unused-but-set-variable]
41 | u64 mchbar_addr;
| ^~~~~~~~~~~
No idea why this showed up now, but it's easy to fix by changing the #ifdef to
an IS_ENABLED() check that the compiler can see through.

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.
