Guennadi,

I made some testing, and there is something I don't understand in the new device
model.
This is the testcase I'm considering :
 - I unload i2c-pxa, pxa-camera, mt9m111, soc-camera modules
 - I load pxa-camera, mt9m111, soc-camera modules
 - I then load i2c-pxa
    => the mt9m111 is not detected
 - I unload and reload mt9m111 and pxa_camera
    => not any better
 - I unload soc_camera, mt9m111, pxa_camera and reload
    => this time the video device is detected

What I'm getting at is that if soc_camera is loaded before the i2c host driver,
no camera will get any chance to work. Is that normal considering the new driver
model ?
I was naively thinking that there would be a "rescan" when the "control" was
being available for a sensor.

Cheers.
