HDMI采集芯片ADV7611，通DM8148的I2C[0]控制，adv7611的驱动编译到了内核里， kernel启动时有：adv7611 1-004c: chip found @ 0x98 (OMAP I2C adapter)；加载ti81xxvin.ko后，adv7611又出现adv7611 3-004c: chip found @ 0x98 (OMAP I2C adapter)。

之后，我修改ti81xxvin_mian.c中i2c_adap = i2c_get_adapter(3); 因为我的adv7611连在dm8148的i2c[0]上，
if (cpu_is_ti814x())
//i2c_adap = i2c_get_adapter(3);
i2c_adap = i2c_get_adapter(1);
重新编译modules后，
root@dm814x-evm:~# insmod ti81xxvin.ko
i2c i2c-1: Failed to register i2c client adv7611 at 0x4c (-16)
ti81xxvin ti81xxvin: Error registering v4l2 subdevice
root@dm814x-evm:~#
又说不能注册adv7611了，还有其他我忽略的地方吗？
是不是视频采集芯片，现在只能挂到dm8148的i2c[2]上？
