The issue has been reported before, when DisplayPort helpers were hidden behind the option CONFIG_DRM_KMS_HELPER. [2]

Thanks for your patch!
This fixes the build errors I'm seeing, so Tested-by: Geert Uytterhoeven geert+renesas@glider.be
Is this planned to be queued? This is still failing in drm-next. Thanks!
Looks like this has been in drm-misc-next since Feb 4:

drm/panel: Select DRM_DP_HELPER for DRM_PANEL_EDP
Maybe it needed to land elsewhere, though?
Sorry about the mess. We had some confusion with this cycle's drm-misc-next pull request, which got delayed significantly. There's been a PR today, which should be merged into drm-next any time now. The patch will be part of that.
Best regards Thomas
