I noticed another thing now this patch showed up in next-20140716.

After this patch that symbol is still referenced in:
drivers/media/platform/Kconfig:159:     depends on VIDEO_DEV && VIDEO_V4L2 && (PLAT_S5P || ARCH_EXYNOS)
drivers/media/platform/Kconfig:169:     depends on VIDEO_DEV && VIDEO_V4L2 && (PLAT_S5P || ARCH_EXYNOS)
drivers/media/platform/Kconfig:177:     depends on VIDEO_DEV && VIDEO_V4L2 && (PLAT_S5P || ARCH_EXYNOS)
drivers/media/platform/exynos4-is/Kconfig:5:    depends on (PLAT_S5P || ARCH_EXYNOS)
drivers/media/platform/s5p-tv/Kconfig:11:       depends on (PLAT_S5P || ARCH_EXYNOS) && PM_RUNTIME
drivers/usb/host/Kconfig:223:       depends on PLAT_S5P || ARCH_EXYNOS
drivers/usb/host/Kconfig:530:   depends on PLAT_S5P || ARCH_EXYNOS

Again, I assume patches to remove these references are pending. But is
that correct?
