The omap_dss_device .enable_hpd() and .disable_hpd() are used to enable and disable hot-plug detection at omapdrm probe and remove time. This is required to avoid reporting hot-plug detection events before the DRM infrastructure is ready to accept them, as that could result in crashes or other malfunction. Hot-plug event reporting is conditioned by both HPD being enabled through the .enable_hpd() operation and by the HPD callback being registered though the .register_hpd_cb() operation. We thus don't need a separate enable operation if we can guarantee that callbacks won't be registered too early. HPD callbacks are registered at connector initialization time, which is too early to start reporting HPD events. There's however nothing blocking a move of callback registration to a later time when the omapdrm driver calls the HPD enable operations. Do so, and remove the HPD enable operation completely from omap_dss_device drivers.
