From bff6efc54bd0e27a332eb733525d7f698fd4a5b7 Mon Sep 17 00:00:00 2001 From: Anup Sharma Date: Sat, 13 May 2023 01:54:34 +0530 Subject: ntb: hw: amd: Fix debugfs_create_dir error checking The debugfs_create_dir function returns ERR_PTR in case of error, and the only correct way to check if an error occurred is 'IS_ERR' inline function. This patch will replace the null-comparison with IS_ERR.
