+/**
148
+ * struct cec_adapter - cec adapter structure
149
+ * @owner:		module owner
150
+ * @name:		name of the CEC adapter
151
+ * @devnode:		device node for the /dev/cecX device
152
+ * @lock:		mutex controlling access to this structure
153
+ * @rc:			remote control device
154
+ * @transmit_queue:	queue of pending transmits
155
+ * @transmit_queue_sz:	number of pending transmits
156
+ * @wait_queue:		queue of transmits waiting for a reply
157
+ * @transmitting:	CEC messages currently being transmitted
158
+ * @transmit_in_progress: true if a transmit is in progress
159
+ * @kthread_config:	kthread used to configure a CEC adapter
160
+ * @config_completion:	used to signal completion of the config kthread
161
+ * @kthread:		main CEC processing thread
162
+ * @kthread_waitq:	main CEC processing wait_queue
163
+ * @ops:		cec adapter ops
164
+ * @priv:		cec driver's private data
165
+ * @capabilities:	cec adapter capabilities
166
+ * @available_log_addrs: maximum number of available logical addresses
167
+ * @phys_addr:		the current physical address
168
+ * @needs_hpd:		if true, then the HDMI HotPlug Detect pin must be high
169
+ *	in order to transmit or receive CEC messages. This is usually a HW
170
+ *	limitation.
171
+ * @is_configuring:	the CEC adapter is configuring (i.e. claiming LAs)
172
+ * @is_configured:	the CEC adapter is configured (i.e. has claimed LAs)
173
+ * @cec_pin_is_high:	if true then the CEC pin is high. Only used with the
174
+ *	CEC pin framework.
175
+ * @adap_controls_phys_addr: if true, then the CEC adapter controls the
176
+ *	physical address, i.e. the CEC hardware can detect HPD changes and
177
+ *	read the EDID and is not dependent on an external HDMI driver.
178
+ *	Drivers that need this can set this field to true after the
179
+ *	cec_allocate_adapter() call.
180
+ * @last_initiator:	the initiator of the last transmitted message.
181
+ * @monitor_all_cnt:	number of filehandles monitoring all msgs
182
+ * @monitor_pin_cnt:	number of filehandles monitoring pin changes
183
+ * @follower_cnt:	number of filehandles in follower mode
184
+ * @cec_follower:	filehandle of the exclusive follower
185
+ * @cec_initiator:	filehandle of the exclusive initiator
186
+ * @passthrough:	if true, then the exclusive follower is in
187
+ *	passthrough mode.
188
+ * @log_addrs:		current logical addresses
189
+ * @conn_info:		current connector info
190
+ * @tx_timeouts:	number of transmit timeouts
191
+ * @notifier:		CEC notifier
192
+ * @pin:		CEC pin status struct
193
+ * @cec_dir:		debugfs cec directory
194
+ * @status_file:	debugfs cec status file
195
+ * @error_inj_file:	debugfs cec error injection file
196
+ * @sequence:		transmit sequence counter
197
+ * @input_phys:		remote control input_phys name
198
+ *
199
+ * This structure represents a cec adapter.
