From d9f7979c92f7b34469c1ca5d1f3add6681fd567c Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Tue, 5 Mar 2019 15:46:09 -0800 Subject: mm: no need to check return value of debugfs_create functions When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this.
