From 0780f3b6f054ec6497a1a16edb9bf5832c0b92f4 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Thu, 13 Jun 2019 17:52:29 +0300 Subject: [PATCH] drm/i915: 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.
