Revision 733f0025f0fb43e382b84db0930ae502099b7e62 authored by Sam Ravnborg on 12 July 2019, 03:52:52 UTC, committed by Linus Torvalds on 12 July 2019, 18:05:41 UTC
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.
