Subject: [PATCH v4 8/9] ethdev: fix possible null pointer access
Date: Fri, 13 May 2022 10:53:56 +0800	[thread overview]
Message-ID: <20220513025357.52275-9-fengchengwen@huawei.com> (raw)
In-Reply-To: <20220513025357.52275-1-fengchengwen@huawei.com>

The rte_tel_data_alloc() may return NULL, so the caller should add
judgement for it.

Fixes: 083b0b310b19 ("ethdev: add common stats for telemetry")
Cc: stable@dpdk.org
