From db50450d096a452ae36dc265575cbff50f0f9f01 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Date: Fri, 14 Jun 2019 09:14:23 +0200 Subject: 6lowpan: 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. Because we don't care if debugfs works or not, this trickles back a bit so we can clean things up by making some functions return void instead of an error value that is never going to fail.
