This timeout can also be 25 * used with CEC_TRANSMIT as the timeout for waiting for a reply. 26 * If 0, then it will use a 1 second timeout instead of waiting 27 * forever as is done with CEC_RECEIVE. 28 * @sequence: The framework assigns a sequence number to messages that are 29 * sent. This can be used to track replies to previously sent 30 * messages. 31 * @flags: Set to 0. 32 * @msg: The message payload. 33 * @reply: This field is ignored with CEC_RECEIVE and is only used by 34 * CEC_TRANSMIT. If non-zero, then wait for a reply with this 35 * opcode. Set to CEC_MSG_FEATURE_ABORT if you want to wait for 36 * a possible ABORT reply.

If reply is non-zero for CEC_TRANSMIT and the message is a 46 * broadcast, then -EINVAL is returned. 47 * if reply is non-zero, then timeout is set to 1000 (the required 48 * maximum response time). 49 * @rx_status: The message receive status bits. Set by the driver. 50 * @tx_status: The message transmit status bits. Set by the driver. 51 * @tx_arb_lost_cnt: The number of 'Arbitration Lost' events.
