stable inclusion from stable-v6.6.8 commit a511e851d49e13835f0da022d48e873c8cc15827 bugzilla: https://gitee.com/openeuler/kernel/issues/I99K53
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
commit 759f14e20891de72e676d9d738eb2c573aa15f52 upstream.
When the separate add modes call was added back in commit c533b5167c7e ("drm/edid: add separate drm_edid_connector_add_modes()"), it failed to address drm_edid_override_connector_update(). Also call add modes there.
