The commit "iommu/vt-d: Probe DMA-capable ACPI name space devices"
introduced a compilation warning due to the "iommu" variable in
for_each_active_iommu() but never used the for each element, i.e,
"drhd->iommu".
drivers/iommu/intel-iommu.c: In function 'probe_acpi_namespace_devices':
drivers/iommu/intel-iommu.c:4639:22: warning: variable 'iommu' set but
not used [-Wunused-but-set-variable]
struct intel_iommu *iommu;
Silence the warning the same way as in the commit d3ed71e5cc
("drivers/iommu/intel-iommu.c: fix variable 'iommu' set but not used")

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.
