From b7088d58dccfba87fe8dd2ab7c493ee1d9d09277 Mon Sep 17 00:00:00 2001 From: Jens Glathe Date: Mon, 8 Jun 2026 06:54:39 +0200 Subject: [PATCH] drm/msm/dp: add missing drm_edid_connector_update() before add_modes on cached EDID After the refactor to struct drm_edid, the fast path in msm_dp_panel_get_modes() that already held a cached EDID called drm_edid_connector_add_modes() directly without first calling drm_edid_connector_update(). The new API requires the update step to associate the EDID with the connector. Add the missing call. This restores correct behaviour for the cached-EDID path.
