From e26ae7c0432101a924cf745b07470c8592de64cb Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Thu, 13 Jun 2019 13:57:49 +0200 Subject: omapdrm: 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.
