Andy Shevchenko 92d4b5e148 ACPI: sysfs: Make sparse happy about address space in use
commit bdd56d7d8931e842775d2e5b93d426a8d1940e33 upstream.

Sparse is not happy about address space in use in acpi_data_show():

drivers/acpi/sysfs.c:428:14: warning: incorrect type in assignment (different address spaces)
drivers/acpi/sysfs.c:428:14:    expected void [noderef] __iomem *base
drivers/acpi/sysfs.c:428:14:    got void *
drivers/acpi/sysfs.c:431:59: warning: incorrect type in argument 4 (different address spaces)
drivers/acpi/sysfs.c:431:59:    expected void const *from
drivers/acpi/sysfs.c:431:59:    got void [noderef] __iomem *base
drivers/acpi/sysfs.c:433:30: warning: incorrect type in argument 1 (different address spaces)
drivers/acpi/sysfs.c:433:30:    expected void *logical_address
drivers/acpi/sysfs.c:433:30:    got void [noderef] __iomem *base

Indeed, acpi_os_map_memory() returns a void pointer with dropped specific
address space. Hence, we don't need to carry out __iomem in acpi_data_show().

README

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.
