Subject: [PATCH] wifi: rtw88: debug: Fix the NULL vs IS_ERR() bug for debugfs_create_file()
Git-commit: 74f7957c9b1b95553faaf146a2553e023a9d1720
Patch-mainline: v6.7-rc1
References: git-fixes
Since debugfs_create_file() return ERR_PTR and never return NULL, so use
IS_ERR() to check it instead of checking NULL.
