## Overview

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

net: ena: Fix error handling in ena_init()

The ena_init() won't destroy workqueue created by
create_singlethread_workqueue() when pci_register_driver() failed.
Call destroy_workqueue() when pci_register_driver() failed to prevent the
resource leak.
