Arnd Bergmann 3397623b37 scsi: pmcraid: use __iomem pointers for ioctl argument
kernelci.org reports a new compile warning for old code in the pmcraid
driver:

arch/mips/include/asm/uaccess.h:138:21: warning: passing argument 1 of '__access_ok' makes pointer from integer without a cast [-Wint-conversion]

The warning got introduced by a cleanup to the access_ok() helper that
requires the argument to be a pointer, where the old version silently
accepts 'unsigned long' arguments as it still does on most other
architectures.

The new behavior in MIPS however seems absolutely sensible, and so far I
could only find one other file with the same issue, so the best solution
seems to be to clean up the pmcraid driver.

This makes the driver consistently use 'void __iomem *' pointers for
passing around the address of the user space ioctl arguments, which gets
rid of the kernelci warning as well as several sparse warnings.

Fixes: f0a955f4ee ("mips: sanitize __access_ok()")

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
