Description

A NULL-pointer dereference vulnerability in the Linux kernel's power sequencing code (pwrseq_device_register) has been fixed. The issue occurs if dev_set_name() fails before initializing the pwrseq->targets list head, leading to pwrseq_release() dereferencing an invalid pointer. The fix moves the dev_set_name() call after the list initialization to prevent this.
