I agree with it, and case of sii8620 shows that there are cases where bridge has no direct access to the connector. On the other side, since you are passing connector to drm_hdmi_avi_infoframe_from_display_mode(), you could drop mode parameter and rename the function to drm_hdmi_avi_infoframe_from_connector() then, unless mode passed and mode set on the connector differs?
