mainlining shenanigans
733f0025f0
When building drm/exynos for sh, as part of an allmodconfig build, the
following warning triggered:
exynos7_drm_decon.c: In function `decon_remove':
exynos7_drm_decon.c:769:24: warning: unused variable `ctx'
struct decon_context *ctx = dev_get_drvdata(&pdev->dev);
The ctx variable is only used as argument to iounmap().
In sh - allmodconfig CONFIG_MMU is not defined
so it ended up in:
\#define __iounmap(addr) do { } while (0)
\#define iounmap __iounmap
Fix the warning by introducing a static inline function for iounmap.
This is similar to several other architectures.

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.
