## Overview

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

usb: gadget: r8a66597: avoid double free of ep0_req in probe error path

If usb_add_gadget_udc() fails, r8a66597_probe() jumps to err_add_udc
and frees ep0_req, then falls through to clean_up2 where ep0_req is
freed again when it is non-NULL.

Remove the redundant free from err_add_udc and keep the cleanup in
clean_up2 so the request is released exactly once.

Issue found using a prototype static analysis tool
and confirmed by code review.
