Subject: [PATCH] qed: Add cleanup in qed_slowpath_start()
Date:   Tue, 13 Aug 2019 05:05:09 -0500
Message-Id: <1565690709-3186-1-git-send-email-wenwen@cs.uga.edu>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

If qed_mcp_send_drv_version() fails, no cleanup is executed, leading to
memory leaks. To fix this issue, redirect the execution to the label 'err3'
before returning the error.
