Subject: [dpdk-stable] [dpdk-dev] [PATCH] baseband/turbo_sw: fix memory leak in error path
Date: Wed, 7 Oct 2020 17:03:38 +0800 [thread overview]
Message-ID: <1cad32e57c8081477a0f448b5b3d61711ef6b382.1602060933.git.wangyunjian@huawei.com> (raw)
From: Yunjian Wang <wangyunjian@huawei.com>
In q_setup() allocated memory for the queue data, we should free
it when error happens, otherwise it will lead to memory leak.
Fixes: b8cfe2c9aed2 ("bb/turbo_sw: add software turbo driver")
Cc: stable@dpdk.org
