From 5c495d6201fb0efafcf6e26b3c82a7bd01ec1b69 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Micha=C5=82=20K=C4=99pie=C5=84?= Date: Wed, 5 Apr 2017 08:49:10 +0200 Subject: [PATCH] platform/x86: fujitsu-laptop: remove redundant fields from struct fujitsu_bl MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The dev field of struct fujitsu_bl is assigned in acpi_fujitsu_bl_add(), but never used afterwards. brightness_changed is set in get_lcd_level() and then its value is only printed in a debug message, so it does not influence execution flow. Remove both fields as they are redundant. Update the aforementioned debug message. Adjust whitespace to make checkpatch happy.
