From d82574a8e5a469b72efaaa134f953a71642217e8 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Wed, 3 Jul 2019 09:01:42 +0200 Subject: [PATCH] cfg80211: 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.
