From 1dbb3bb8de88dbca78556684e79a0f10f7da3d00 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Tue, 18 Jun 2019 17:58:09 +0200 Subject: watchdog: bcm_kona_wdt: 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.
