From 226a893bbb1f4495d7139fd57143475ada0de61d Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Thu, 3 Jan 2019 17:45:58 +0100 Subject: microblaze: 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.
