From mboxrd@z Thu Jan 1 00:00:00 1970 From: =?UTF-8?q?Micha=C5=82=20K=C4=99pie=C5=84?= Subject: [PATCH v2 2/3] platform/x86: fujitsu-laptop: simplify call_fext_func() Date: Wed, 5 Apr 2017 08:50:22 +0200 Message-ID: <20170405065023.3267-3-kernel@kempniu.pl> References: <20170405065023.3267-1-kernel@kempniu.pl> Mime-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Return-path: In-Reply-To: <20170405065023.3267-1-kernel@kempniu.pl> Sender: linux-kernel-owner@vger.kernel.org To: Jonathan Woithe , Darren Hart , Andy Shevchenko Cc: platform-driver-x86@vger.kernel.org, linux-kernel@vger.kernel.org List-Id: platform-driver-x86.vger.kernel.org acpi_evaluate_integer() takes a pathname parameter which contains the name of the entity to evaluate underneath the given handle, so calling acpi_get_handle() beforehand is redundant. Replace the call to acpi_get_handle() with a call to acpi_evaluate_integer(), thus eliminating the need for a local variable storing the handle. Update debug message to reflect this change. Adjust whitespace to make checkpatch happy.
