Subject: [PATCH v2] net/memif: remove pointer deference before null check
Date: Wed, 9 Feb 2022 15:39:34 +0800 [thread overview]
Message-ID: <tencent_7F46CC1FCFE7295F8495CEF137EAC8AE0806@qq.com> (raw)
In-Reply-To: <tencent_0E1B224731F03CA9A76D11653A7EDF322308@qq.com>
There are duplicates of assignment here, the one before null check
may cause a null pointer deference, so remove the previous one.
Fixes: 09c7e63a71f9 ("net/memif: introduce memory interface PMD")
