+/**
+ * struct cec_adapter - cec adapter structure
+ * @owner: module owner
+ * @name: name of the CEC adapter
+ * @devnode: device node for the /dev/cecX device
+ * @lock: mutex controlling access to this structure
+ * @rc: remote control device
+ * @transmit_queue: queue of pending transmits
+ * @transmit_queue_sz: number of pending transmits
+ * @wait_queue: queue of transmits waiting for a reply
+ * @transmitting: CEC messages currently being transmitted
+ * @transmit_in_progress: true if a transmit is in progress
+ * @kthread_config: kthread used to configure a CEC adapter
+ * @config_completion: used to signal completion of the config kthread
+ * @kthread: main CEC processing thread
+ * @kthread_waitq: main CEC processing wait_queue
+ * @ops: cec adapter ops
+ * @priv: cec driver's private data
+ * @capabilities: cec adapter capabilities
+ * @available_log_addrs: maximum number of available logical addresses
+ * @phys_addr: the current physical address
+ * @needs_hpd: if true, then the HDMI HotPlug Detect pin must be high
+ * in order to transmit or receive CEC messages. This is usually a HW
+ * limitation.
+ * @is_configuring: the CEC adapter is configuring (i.e. claiming LAs)
+ * @is_configured: the CEC adapter is configured (i.e. has claimed LAs)
+ * @cec_pin_is_high: if true then the CEC pin is high. Only used with the
+ * CEC pin framework.
+ * @adap_controls_phys_addr: if true, then the CEC adapter controls the
+ * physical address, i.e. the CEC hardware can detect HPD changes and
+ * read the EDID and is not dependent on an external HDMI driver.
+ * Drivers that need this can set this field to true after the
+ * cec_allocate_adapter() call.
+ * @last_initiator: the initiator of the last transmitted message.
+ * @monitor_all_cnt: number of filehandles monitoring all msgs
+ * @monitor_pin_cnt: number of filehandles monitoring pin changes
+ * @follower_cnt: number of filehandles in follower mode
+ * @cec_follower: filehandle of the exclusive follower
+ * @cec_initiator: filehandle of the exclusive initiator
+ * @passthrough: if true, then the exclusive follower is in
+ * passthrough mode.
+ * @log_addrs: current logical addresses
+ * @conn_info: current connector info
+ * @tx_timeouts: number of transmit timeouts
+ * @notifier: CEC notifier
+ * @pin: CEC pin status struct
+ * @cec_dir: debugfs cec directory
+ * @status_file: debugfs cec status file
+ * @error_inj_file: debugfs cec error injection file
+ * @sequence: transmit sequence counter
+ * @input_phys: remote control input_phys name
+ *
+ * This structure represents a cec adapter.
