Even if bus is not hot-pluggable, the devices can be unbound from the
driver via sysfs, so we should not be using __exit annotations on
remove() methods. The only exception is drivers registered with
platform_driver_probe() which specifically disables sysfs bind/unbind
attributes.

This looks correct, but don't we also have to remove __init from 
omap1_cam_probe()? Or would that be a separate patch?

Thanks
