From ae503ab04913794b12e1939caa75aa091062a1b3 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Tue, 22 Jan 2019 16:21:42 +0100 Subject: [PATCH] timekeeping/debug: 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.
