But added the dependency as depends on !VIDEO_SAMSUNG_S5P_G2D which isn't correct since Kconfig expressions are not boolean but tristate. So it will only evaluate to 'n' if VIDEO_SAMSUNG_S5P_G2D=y but it 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.
