Subject: [dpdk-stable] [dpdk-dev] [PATCH] crypto/ccp: fix fd leak on probe failure
Date: Sun, 26 Apr 2020 14:36:15 +0800	[thread overview]
Message-ID: <1587882975-13960-1-git-send-email-wangyunjian@huawei.com> (raw)

From: Yunjian Wang <wangyunjian@huawei.com>

Zero is a valid fd. When ccp_probe_device() is failed, the uio_fd won't be
closed thus leading fd leak.

Fixes: ef4b04f87fa6 ("crypto/ccp: support device init")
Cc: stable@dpdk.org
