At OLS we reviewed how CRDA [1] and its integration with the kernel works. One comment was to have the kernel call a uevent instead of calling call_usermodehelper() as this is a better accepted way of calling user mode helpers and it provides a better framework. I still am not sold on this but regardless I'd like to give it a shot. It seems we would need to register a class for this. Marcel I know you also mentioned about using device platform for this? Is this correct or did I misunderstand? Can you elaborate a bit?
