Subject: [PATCH -next] RDMA/core: Remove NULL check before dev_{put, hold}
Date: Tue, 24 Oct 2023 08:38:15 +0800	[thread overview]
Message-ID: <20231024003815.89742-1-yang.lee@linux.alibaba.com> (raw)

The call netdev_{put, hold} of dev_{put, hold} will check NULL,
so there is no need to check before using dev_{put, hold},
remove it to silence the warning:

./drivers/infiniband/core/nldev.c:375:2-9: WARNING: NULL check before dev_{put, hold} functions is not needed.

Reported-by: Abaci Robot <abaci@linux.alibaba.com>
Closes: https://bugzilla.openanolis.cn/show_bug.cgi?id=7047
Signed-off-by: Yang Li <yang.lee@linux.alibaba.com>
