From 7cd310f3fda3605caaa947221e8838eac5f2e45f Mon Sep 17 00:00:00 2001 From: "gregkh@linuxfoundation.org" Date: Fri, 3 Nov 2017 15:47:04 +0100 Subject: [PATCH] staging: unisys: don't care about debugfs errors A caller should never care about a debugfs error return value, and it should never abort its normal operation if something "odd" goes on. Fix up the unisys init code to not care if the root debugfs directory for the subsystem is created or not, as no place it is used will matter.
