Subject: LoongArch: Fix debugfs_create_dir() error checking
From: Immad Mir <mirimmad17@xxxxxxxxx>
commit 41efbb682de1231c3f6361039f46ad149e3ff5b9 upstream.
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.
