Probably this part of the patch should be removed. If not, reworked so it is <= 80 columns wide. Otherwise, this patch looks good to me. > atomic_inc(&bna_debugfs_port_count); > > for (i = 0; i < ARRAY_SIZE(bnad_debugfs_files); i++) { > @@ -523,12 +516,6 @@ bnad_debugfs_init(struct bnad *bnad) > bnad->port_debugfs_root, > bnad, > file->fops); > - if (!bnad->bnad_dentry_files[i]) { > - netdev_warn(bnad->netdev, > - "create %s entry failed\n", > - file->name); > - return; > - } > } > } > }

Driver bna can work fine even if any previous call to debugfs create APIs failed. All return value checks of them should be dropped, as debugfs APIs say.
