Subject: [PATCH 44/44] net/mlx5e: CT: Fix memory leak in cleanup

From: Eli Britstein <[email-masked]>
Date: Sun, 28 Jun 2020 15:42:26 +0300

[ Upstream commit eb32b3f53d283e8d68b6d86c3a6ed859b24dacae ]

CT entries are deleted via a workqueue from netfilter. If removing the
module before that, the rules are cleaned by the driver itself, but the
memory entries for them are not freed. Fix that.
