From e24775e41ffc59d9ae8c1f2a9a4ff9f79db0e573 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Tue, 23 Jul 2013 18:36:47 +0300 Subject: [PATCH] dmatest: remove IS_ERR_OR_NULL checks of debugfs calls There is a really little chance when we are able to create a directory and are not able to create nodes under it. So, this patch just removes those checks.
