2 | /* Keytable for the CEC remote control |
3 | * |
4 | * This keymap is unusual in that it can't be built as a module, |
5 | * instead it is registered directly in rc-main.c if CONFIG_MEDIA_CEC_RC |
6 | * is set. This is because it can be called from drm_dp_cec_set_edid() via |
7 | * cec_register_adapter() in an asynchronous context, and it is not |
8 | * allowed to use request_module() to load rc-cec.ko in that case. |
9 | * |
10 | * Since this keymap is only used if CONFIG_MEDIA_CEC_RC is set, we |
11 | * just compile this keymap into the rc-core module and never as a |
12 | * separate module. |
