With CONFIG_DRM_PANEL_EDP=y and CONFIG_DRM_KMS_HELPER=m the compilation fails: drivers/gpu/drm/panel/panel-edp.c:843: undefined reference to `drm_panel_dp_aux_backlight' Add a dependency on DRM_KMS_HELPER to fix this. Signed-off-by: Luca Weiss <luca@xxxxxxxxx> --- I briefly tried "select DRM_KMS_HELPER" but that causes a circular dependency.
