From c4b43d8336e52dce6d124e428aa3b71703e62647 Mon Sep 17 00:00:00 2001 From: Yang Ruibin <11162571@vivo.com> Date: Wed, 21 Aug 2024 04:39:08 -0400 Subject: drivers:iio:Fix the NULL vs IS_ERR() bug for debugfs_create_dir() The debugfs_create_dir() function returns error pointers. It never returns NULL. So use IS_ERR() to check it.
