Commit aeefb36832e5 ("drm/exynos: gsc: add device tree support and remove usage of static mappings") made the DRM_EXYNOS_GSC Kconfig symbol to only be selectable if the exynos-gsc V4L2 driver isn't enabled, since both use the same HW IP block.
But added the dependency as depends on !VIDEO_SAMSUNG_EXYNOS_GSC which is not correct since Kconfig expressions are not boolean but tristate. So it will only evaluate to 'n' if VIDEO_SAMSUNG_EXYNOS_GSC=y but will evaluate to 'm' if VIDEO_SAMSUNG_S5P_G2D=m.
This means that both the V4L2 and DRM drivers can be enabled if the former is enabled as a module, which is not what we want.
