From 41efbb682de1231c3f6361039f46ad149e3ff5b9 Mon Sep 17 00:00:00 2001 From: Immad Mir Date: Thu, 15 Jun 2023 14:35:56 +0800 Subject: LoongArch: Fix debugfs_create_dir() error checking The debugfs_create_dir() returns ERR_PTR in case of an error and the correct way of checking it is using the IS_ERR_OR_NULL inline function rather than the simple null comparision. This patch fixes the issue.
