From 5a7bb7ce26a98d52190086ae6174becedf03bf43 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Fri, 14 Jun 2019 08:59:34 +0200 Subject: mac80211: 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. Cc: Johannes Berg Cc: "David S.
