Subject: [PATCH] ntb: hw: amd: Fix debugfs_create_dir error checking
Date: Sat, 13 May 2023 01:54:34 +0530 [thread overview]
Message-ID: <ZF6ggnry8BVjQyYE@yoga> (raw)
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.
