^^^^^^^^^^^^^^^^
I think this comment is not necessary, it's also highly unusual. On
other words: other patches like this don't add such comments.
You can always use "git blame" to find out why some line has changed the
way it changed ...

I thought it might be useful since this dependency is not for the driver but for selected item.

Indeed that would make sense... but now after some more looking at it, even this patch is not needed. All these drivers are children of MEDIA_SUPPORT which already depends on HAS_IOMEM.

The MFD_SYSCON depends on HAS_IOMEM so when selecting it avoid unmet direct dependencies. Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> --- Changes since v1: 1. Fix comments from Arnd: VIDEO_OMAP3 does not require it, however VIDEO_S5P_FIMC still needs it. --- drivers/media/platform/exynos4-is/Kconfig | 1 + 1 file changed, 1 insertion(+)
