[ Upstream commit 61ae7f8694fb4b57a8c02a1a8d2b601806afc999 ]
__iomem attribute is supposed to be used only with variables holding the
MMIO pointer. But here, 'mw_addr' variable is just holding a 'void *'
returned by pci_epf_alloc_space(). So annotating it with __iomem is clearly
wrong. Hence, drop the attribute.
This also fixes the below sparse warning:
drivers/pci/endpoint/functions/pci-epf-vntb.c:524:17: warning: incorrect type in assignment (different address spaces)
drivers/pci/endpoint/functions/pci-epf-vntb.c:524:17: expected void [noderef] __iomem *mw_addr

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.
