-/** 
- * 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.

+ * 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.
