/**
* struct cec_msg - CEC message structure .
* @ tx_ts : Timestamp in nanoseconds using CLOCK_MONOTONIC . Set by the
* driver when the message transmission has finished .
* @ rx_ts : Timestamp in nanoseconds using CLOCK_MONOTONIC . Set by the
* driver when the 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 .
* @ 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 ) .
* @ rx_status : The message receive status bits . Set by the driver .
* @ tx_status : The message transmit status bits . Set by the driver .
* @ 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 .
