From babebd1dc1279027206583a9921e05657f97da87 Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Fri, 5 Jan 2024 18:57:49 +0200 Subject: [PATCH] drm/probe-helper: remove unused drm_connector_helper_get_modes_from_ddc() Remove the unused drm_connector_helper_get_modes_from_ddc() function. Most drivers should probably have this functionality split to detect and get modes parts, so the helper is not the best abstraction.
