Remove the assert from the callback priv lookup function since it does not require RTNL lock and is already protected by flow_indr_block_lock. This will avoid warnings from being emitted to dmesg if the driver registers its callback after an ingress qdisc was created for a netdevice. The warnings started after the following patch was merged: commit 74fc4f828769 ("net: Fix offloading indirect devices dependency on qdisc order creation") Signed-off-by: Eli Cohen <elic@nvidia.com> --- drivers/net/ethernet/broadcom/bnxt/bnxt_tc.c | 3 --- drivers/net/ethernet/mellanox/mlx5/core/en/rep/tc.c | 3 --- drivers/net/ethernet/netronome/nfp/flower/offload.c | 3 --- 3 files changed, 9 deletions(-)
