drm/panel: s6e3ha8: fix unmet dependency on DRM_DISPLAY_HELPER

[PATCH] drm/panel: s6e3ha8: fix unmet dependency on DRM_DISPLAY_HELPER

Posted by Julian Braha 1 week, 6 days ago

Currently, DRM_PANEL_SAMSUNG_S6E3HA8 selects DRM_DISPLAY_DSC_HELPER
without ensuring its dependency, DRM_DISPLAY_HELPER, is enabled,
causing an unmet dependency.

Let's select DRM_DISPLAY_HELPER as other similar options do.

This unmet dependency bug was found by kconfirm, a static analysis tool
for Kconfig.
