Subject: [PATCH] ath5k: Fix debugfs_create_dir error checking
Date: Sun, 30 Jul 2023 19:38:20 -0700 [thread overview]
Message-ID: <20230731023820.26571-1-rauji.raut@gmail.com> (raw)
The debugfs_create_dir function returns ERR_PTR
in case of error and the correct way to check an
error is 'IS_ERR' inline function.
This patch will replace the null-comparison with IS_ERR
This issue was found with the help of Coccinelle.
