The next patchset providing the multiple drivers support will add to the per cpu sysfs driver.
In order to prepare the place this patch creates a single entry function when a cpuidle device is added or removed.

This is a simple rename, as far as I can say, and it's better to include it into the patchset introducing the support for multiple drivers.
Thanks, Rafael
