| Subject: net/mlx5: Continue driver initialization despite debugfs failure |
| |
| commit 199fa087dc6b503baad06712716fac645a983e8a upstream. |
| |
| The failure to create debugfs entry is unpleasant event, but not enough |
| to abort drier initialization. Align the mlx5_core code to debugfs design |
| and continue execution whenever debugfs_create_dir() successes or not. |
| |
| Fixes: e126ba97dba9 ("mlx5: Add driver for Mellanox Connect-IB adapters") |
