From fecb0d95cdf752836cafdfffc1661f61ba4e2101 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Wed, 12 Jun 2019 17:35:13 +0200 Subject: [PATCH] debugobjects: No need to check return value of debugfs_create() 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.
