Subject: [PATCH net-next] net: x25: Use list_for_each_entry() to simplify code in x25_route.c
Date: Thu, 10 Jun 2021 20:48:26 +0800 [thread overview]
Message-ID: <20210610124826.3833818-1-wanghai38@huawei.com> (raw)
Convert list_for_each() to list_for_each_entry() where
applicable. This simplifies the code.
