Subject: [PATCH v2 -next] infiniband: core: Delete useless kfree code
Date: Wed, 16 Dec 2020 16:02:19 +0800	[thread overview]
Message-ID: <20201216080219.18184-1-zhengyongjun3@huawei.com> (raw)

The parameter of kfree function is NULL, so kfree code is useless, delete it.
Therefore, goto expression is no longer needed, so simplify it.
