| D | v4l2-framework.txt | 84 该框架非常类似驱动结构：它有一个 v4l2_device 结构用于保存设备
89 V4L2 框架也可与媒体框架整合（可选的）。如果驱动设置了 v4l2_device
93 v4l2_device 结构体
96 每个设备实例都通过 v4l2_device (v4l2-device.h)结构体来表示。
102 v4l2_device_register(struct device *dev, struct v4l2_device *v4l2_dev);
104 注册操作将会初始化 v4l2_device 结构体。如果 dev->driver_data 域
108 v4l2_device 结构体实例的驱动特定设备结构体。这可以在注册 V4L2 设备
109 实例前通过 dev_set_drvdata() 函数完成。同时必须设置 v4l2_device
131 注销 v4l2_device 使用如下函数：
133 v4l2_device_unregister(struct v4l2_device *v4l2_dev);
