From a106504ba7aa4d738a52676e3e0c43fce9f2ba03 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Thu, 13 Jun 2019 15:28:29 +0200 Subject: [PATCH] malidp: 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.
