When RDMA device registration fails, the registration\nworker's err_dealloc_ctx path calls c4iw_dealloc() directly, bypassing\nc4iw_remove(), so the debugfs dentries leak and outlive the freed\nc4iw_dev.\n\nMove debugfs_remove_recursive() into c4iw_dealloc() so every path that\nfrees ctx->dev also removes its debugfs tree."
