	When auxiliary_device_add() returns an error, auxiliary_device_uninit() is called, which causes refcount for device to be decremented and .release callback will be triggered. Because adev_release() re-calls auxiliary_device_uninit(), it will cause use-after-free: [ 1269.455172] WARNING: CPU: 0 PID: 14267 at lib/refcount.c:28 refcount_warn_saturate+0x110/0x15 [ 1269.464007] refcount_t: underflow; use-after-free.

2022-02-09	peci: Add peci-cpu driver	Iwona Winiarska	1	-0/+343
	PECI is an interface that may be used by different types of devices. Add a peci-cpu driver compatible with Intel processors. The driver is responsible for handling auxiliary devices that can subsequently be used by other drivers (e.g. hwmons).
