From 2d146b924ec3c0873f06308d149684dc1105d9a3 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Tue, 22 Jan 2019 16:21:07 +0100 Subject: backing-dev: 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. And as the return value does not matter at all, no need to save the dentry in struct backing_dev_info, so delete it.
