Subject: [PATCH 3/5] net/hns3: fix loop code variable type mismatch
Date: Thu, 18 May 2023 19:29:42 +0800	[thread overview]
Message-ID: <20230518112944.32276-4-liudongdong3@huawei.com> (raw)
In-Reply-To: <20230518112944.32276-1-liudongdong3@huawei.com>

From: Dengdui Huang <huangdengdui@huawei.com>

Loop conditions are compared with different variable types,
which may cause overflow risks.
