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.

Forgot to add, this is the closest "Fixes" I can find, before that commit with arm32 qcom_defconfig both beforementioned options were builtin
Fixes: 9d6366e743f3 ("drm: fb_helper: improve CONFIG_FB dependency")
