+Subject: drm/panel: Select DRM_DP_HELPER for DRM_PANEL_EDP
+
+From: Thomas Zimmermann <tzimmermann@suse.de>
+
+commit 3755d35ee1d2454b20b8a1e20d790e56201678a4 upstream.
+
+As reported in [1], DRM_PANEL_EDP depends on DRM_DP_HELPER. Select
+the option to fix the build failure. The error message is shown
+below.
+
+  arm-linux-gnueabihf-ld: drivers/gpu/drm/panel/panel-edp.o: in function
+    `panel_edp_probe': panel-edp.c:(.text+0xb74): undefined reference to
+    `drm_panel_dp_aux_backlight'
+  make[1]: *** [/builds/linux/Makefile:1222: vmlinux] Error 1
+
+The issue has been reported before, when DisplayPort helpers were
+hidden behind the option CONFIG_DRM_KMS_HELPER. [2]
+
+v2:
+       * fix and expand commit description (Arnd)
