In the Linux kernel, the following vulnerability has been resolved:
fbdev: efifb: Register sysfs groups through driver core
The driver core can register and cleanup sysfs groups already.
Make use of that functionality to simplify the error handling and
cleanup.
Also avoid a UAF race during unregistering where the sysctl attributes
were usable after the info struct was freed.
