From d5ddd5a51726f46d9f2a119c461ab28ca09b9e69 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Tue, 22 Jan 2019 15:41:13 +0100 Subject: arm: omap1: 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.
