/**
* struct cec_msg - CEC message structure.
* @ts: Timestamp in nanoseconds using CLOCK_MONOTONIC. Set by the
* driver. It is set when the message transmission has finished
* and it is set when a message was received.
* @len: Length in bytes of the message.
* @timeout: The timeout (in ms) that is used to timeout CEC_RECEIVE.
* Set to 0 if you want to wait forever. This timeout can also be
* used with CEC_TRANSMIT as the timeout for waiting for a reply.
* If 0, then it will use a 1 second timeout instead of waiting
* forever as is done with CEC_RECEIVE.
* @sequence: The framework assigns a sequence number to messages that are
* sent. This can be used to track replies to previously sent
* messages.
* @flags: Set to 0.
* @rx_status: The message receive status bits. Set by the driver.
* @tx_status: The message transmit status bits. Set by the driver.
* @msg: The message payload.
* @reply: This field is ignored with CEC_RECEIVE and is only used by
* CEC_TRANSMIT. If non-zero, then wait for a reply with this
* opcode. Set to CEC_MSG_FEATURE_ABORT if you want to wait for
* a possible ABORT reply. If there was an error when sending the
* msg or FeatureAbort was returned, then reply is set to 0.
* If reply is non-zero upon return, then len/msg are set to
* the received message.
* If reply is zero upon return and status has the
* CEC_TX_STATUS_FEATURE_ABORT bit set, then len/msg are set to
* the received feature abort message.
* If reply is zero upon return and status has the
* CEC_TX_STATUS_MAX_RETRIES bit set, then no reply was seen at
* all. If reply is non-zero for CEC_TRANSMIT and the message is a
* broadcast, then -EINVAL is returned.
* if reply is non-zero, then timeout is set to 1000 (the required
* maximum response time).
* @tx_arb_lost_cnt: The number of 'Arbitration Lost' events. Set by the driver.
* @tx_nack_cnt: The number of 'Not Acknowledged' events. Set by the driver.
* @tx_low_drive_cnt: The number of 'Low Drive Detected' events. Set by the
* driver.
* @tx_error_cnt: The number of 'Error' events. Set by the driver.
