From f095adba36bb7f6947135f6893b5837760961b3d Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Wed, 12 Jun 2019 17:22:04 +0200 Subject: [PATCH] orangefs: 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.
