## Overview

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

usb: gadget: f_eem: Fix memory leak in eem_unwrap

The existing code did not handle the failure case of usb_ep_queue in the
command path, potentially leading to memory leaks.

Improve error handling to free all allocated resources on usb_ep_queue
failure. This patch continues to use goto logic for error handling, as the
existing error handling is complex and not easily adaptable to auto-cleanup
helpers.
