scsi: lpfc: Release hbalock before calling lpfc_worker_wake_up()
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Release hbalock before calling lpfc_worker_wake_up() lpfc_worker_wake_up() calls the lpfc_work_done() routine, which takes the hbalock.
