The pointer to 'struct v4l2_subdev' is stored in drvdata via v4l2_i2c_subdev_init() so there is no point of a dance like: struct i2c_client *client = to_i2c_client(struct device *dev) struct v4l2_subdev *sd = i2c_get_clientdata(client); This allows to remove local variable 'client' and few pointer dereferences.
