From 5efc800463bc340abf6b5e7abd84f7a9522a428d Mon Sep 17 00:00:00 2001 From: =?utf8?q?Micha=C5=82=20K=C4=99pie=C5=84?= Date: Wed, 1 Mar 2017 07:42:53 +0100 Subject: [PATCH] platform/x86: fujitsu-laptop: decrease indentation in acpi_fujitsu_bl_notify() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit acpi_fujitsu_bl_notify() is pretty deeply nested, which hurts readability. Strip off one level of indentation by returning early when the event code supplied as argument is not ACPI_FUJITSU_NOTIFY_CODE1.
