sh: prevent warnings when using iounmap
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.
