Hi, I am having trouble with adding sysfs support to my driver targeted at 2.6.19.2. Using kobject_add() and passing in NULL for parent I can add a directory which shows up in /sys. I can then add files(attributes) and the associated functions to be able to read and write to it. That is all fine.

What do I pass in for parent if I want my directory to be in /sys/devices/system? It needs to be a pointer to a struct kobject. How do I find the correct kobject to use as my parent?

thanks
