From: Andy Shevchenko Subject: [PATCH v5 2/5] x86: pmc_atom: don't check for NULL twice Date: Wed, 14 Jan 2015 18:39:32 +0200 Message-ID: <1421253575-22509-3-git-send-email-andriy.shevchenko@linux.intel.com> References: <1421253575-22509-1-git-send-email-andriy.shevchenko@linux.intel.com> Return-path: In-Reply-To: <1421253575-22509-1-git-send-email-andriy.shevchenko@linux.intel.com> Sender: linux-kernel-owner@vger.kernel.org To: x86@kernel.org, Aubrey Li , "Rafael J . Wysocki" , "Kumar P, Mahesh" , linux-kernel@vger.kernel.org, linux-acpi@vger.kernel.org Cc: Andy Shevchenko List-Id: linux-acpi@vger.kernel.org debugfs_remove_recursive() is NULL-aware, thus, we may safely remove the check here. There is no need to assing NULL to variable since it will be not used anywhere.
