A kobject is meant to manage the lifecycle of some resource. However the module sysfs code only creates a kobject to get a "notes" subdirectory in sysfs. This can be achieved easier and cheaper by using a sysfs group. Switch the notes attribute code to such a group, similar to how the section allocation in the same file already works.
