Hence add a dependency on DRM_RCAR_DU, to prevent asking the user about this driver when configuring a kernel without R-Car Display Unit support, like is already done for DRM_RCAR_CMM. Fixes: 42d95d1b3a9c649b ("drm/rcar: stop using 'imply' for dependencies") Signed-off-by: Geert Uytterhoeven --- The problem pre-existed before commit 42d95d1b3a9c649b, as the dependency of DRM_RCAR_LVDS on DRM_RCAR_DU was accidentally removed before.
