/* Keytable for the CEC remote control
 *
 * This keymap is unusual in that it can't be built as a module,
 * instead it is registered directly in rc-main.c if CONFIG_MEDIA_CEC_RC
 * is set. This is because it can be called from drm_dp_cec_set_edid() via
 * cec_register_adapter() in an asynchronous context, and it is not
 * allowed to use request_module() to load rc-cec.ko in that case.
 *
 * Since this keymap is only used if CONFIG_MEDIA_CEC_RC is set, we
 * just compile this keymap into the rc-core module and never as a
 * separate module.
