From 316bcda81d29059751daf9a81d8ccc1c041d08c8 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Tue, 22 Jan 2019 16:17:59 +0100 Subject: [PATCH] infiniband: usnic: 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.
