标题: linux 3.1.452 设备数更改
更改了设备数文件的I2C ，ov5642原来的I2C在i2c1 上，我给改到i2c2 上，现在能够通信但是无法通过V4l2读取图像。
读到camera寄存器值显示已有数据流产生
ar0132_power_on(&client->dev);

1-0048 supply DOVDD not found, using dummy regulator
1-0048 supply DVDD not found, using dummy regulator
1-0048 supply AVDD not found, using dummy regulator
会有影响吗？
