From 82d4afcfa9b507c983bb261ad1d6d13cb52d6e06 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Tue, 16 Feb 2021 15:46:42 +0100 Subject: USB: host: sl811: remove dentry pointer for debugfs There is no need to keep the dentry pointer around for the created debugfs file, as it is only needed when removing it from the system. When it is to be removed, ask debugfs itself for the pointer, to save on storage and make things a bit simpler.
