I found this when testing Dragon-board 410c which uses this bridge
[    6.671913] msm 1a00000.mdss: [drm:msm_dsi_manager_ext_bridge_init [msm]] *ERROR* drm_bridge_connector_init failed: -22
[    6.678879] msm 1a00000.mdss: [drm:msm_dsi_modeset_init [msm]] *ERROR* failed to create dsi connector: -19
