Subject: [PATCH] cfg80211: no need to check return value of debugfs_create functions
Git-commit: d82574a8e5a469b72efaaa134f953a71642217e8
Patch-mainline: v5.4-rc1
References: jsc#SLE-13430
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.
