struct v4l2_subdev *sd = i2c_get_clientdata(client);
-Finally you need to make a command function to make driver->command()
-call the right subdev_ops functions:
-
-static int subdev_command(struct i2c_client *client, unsigned cmd, void *arg)
-{
- return v4l2_subdev_command(i2c_get_clientdata(client), cmd, arg);

-If driver->command is never used then you can leave this out. Eventually the
-driver->command usage should be removed from v4l.

Make sure to call v4l2_device_unregister_subdev(sd) when the remove() callback
is called. This will unregister the sub-device from the bridge driver. It is
safe to call this even if the sub-device was never registered.
