Subject: [PATCH] drm/amd/display: assign edid_blob_ptr with edid from debugfs
[Why] implementation change of drm_edid_override_set since linux
kernel 6.1, edid from debugfs is saved into connector->edid_override
immediatey, not saved to connector->edid_blob_ptr at the same time.
[How] call new drm_edid function drm_connector_update_edid_property
to assign connector->edid_blob_ptr with override edid from debugfs.
