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.
