3.16.65-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Leon Romanovsky <leonro@xxxxxxxxxxxx> 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.
