From 7449ca87312a5b0390b765be65a126e6e5451026 Mon Sep 17 00:00:00 2001 From: Alexander Egorenkov Date: Fri, 26 Feb 2021 11:21:05 +0100 Subject: [PATCH] s390/zcore: 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. See commit 7dd541a3fb34 ("s390: no need to check return value of debugfs_create functions").
