From 71cae9ad42168ab5ed21af5e068d45e712e5cc75 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Tue, 29 May 2018 17:30:49 +0200 Subject: USB: mtu3: no need to check return value of debugfs_create_dir() 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.
