---|
| 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. |
