Subject: [PATCH net-next] team: Remove NULL check before dev_{put, hold}
Date:   Thu, 27 Jul 2023 08:57:41 +0800

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/net/team/team.c:2325:3-10: WARNING: NULL check before dev_{put, hold} functions is not needed.
