What prevents you from following what has been done for drivers/usb/core/ledtrig-usbport.c? Use sysfs_create_group() for creating color dir and sysfs_add_file_to_group() for adding files to it.
We have nested directories here. colors is a directory and then the LED color is a directory.
So I am not sure how to create a group under another group without the colors directory kobj.
Wondering if you know of any examples? Dan
