Actually the attributes use own loops for this too.
In theory could add a group in the middle, but it would greatly complicate the driver interface for little gain.
In theory the low loops could be shared between the group code and sysfs_create_files(), but I'm not sure it's really worth it because it's just a few lines of code (which are currently duplicated in multiple places anyways, so it's a net-win)
You still want me to attempt that?
