From f9d5de4064e57017b75cfed9c7cfdff73bb52681 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Thu, 13 Jun 2019 20:37:53 +0200 Subject: thermal: tegra: 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.
