The struct pci_filp_private has no users outside drivers/pci/proc.c and is only used when HAVE_PCI_MMAP is defined. Wrap the struct pci_filp_private definition itself in #ifdef HAVE_PCI_MMAP. Found by cppcheck: $ cppcheck --enable=all --force drivers/pci/proc.c drivers/pci/proc.c:192:6: style: struct member 'pci_filp_private::write_combine' is never 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.
