/* 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.
