From 17e23555616116e1668e83029d26354c2479c78b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Micha=C5=82=20K=C4=99pie=C5=84?= Date: Mon, 3 Apr 2017 11:38:58 +0200 Subject: [PATCH] platform/x86: fujitsu-laptop: simplify call_fext_func() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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. Adjust whitespace to make checkpatch happy.
