^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36) Using this ioctl an application can learn which HDMI connector this CEC
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) device corresponds to. While calling this ioctl the application should
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38) provide a pointer to a cec_connector_info struct which will be populated
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39) by the kernel with the info provided by the adapter's driver. This ioctl
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 40) is only available if the ``CEC_CAP_CONNECTOR_INFO`` capability is set.
