* @name: Indicates the type of the device, usually a chip name that's
* generic enough to hide second-sourcing and compatible revisions.
* @adapter: manages the bus segment hosting this I2C device
+ * @driver: device's driver, hence pointer to access routines
+ * @usage_count: counts current number of users of this client
* @dev: Driver model device node for the slave.
* @irq: indicates the IRQ generated by this device (if any)
* @driver_name: Identifies new-style driver used with this device; also
* used as the module name for hotplug/coldplug modprobe support.
+ * @list: list of active/busy clients
+ * @released: used to synchronize client releases & detaches and references
*
* An i2c_client identifies a single device (i.e. chip) connected to an
* i2c bus. The behaviour exposed to Linux is defined by the driver
