## Overview

In the Linux kernel, the following vulnerability has been resolved:

scsi: qla2xxx: Perform lockless command completion in abort path

While adding and removing the controller, the following call trace was
observed:

The command was completed in the abort path during driver unload with a
lock held, causing the warning in abort path. Hence complete the command
without any lock held.
