If auxiliary_device_add() fails, the release callback will be\ncalled twice, resulting in a UAF. Due to timing, the auxdev code in this\ndriver \"took inspiration\" from the aforementioned commit, and thus its\nbugs too!\n\nMoving auxiliary_device_uninit() to the unregister callback instead\navoids the issue."
