Description

In the Linux kernel, the following vulnerability has been resolved:\nACPI: battery: Fix possible crash when unregistering a battery hook\nWhen a battery hook returns an error when adding a new battery, then\nthe battery hook is automatically unregistered.\nHowever the battery hook provider cannot know that, so it will later\ncall battery_hook_unregister() on the already unregistered battery\nhook, resulting in a crash.\nFix this by using the list head to mark already unregistered battery\nhooks as already being unregistered so that they can be ignored by\nbattery_hook_unregister().
