From d75a4a972ad1ed6d1326c63ae2fb0f9586161b4d Mon Sep 17 00:00:00 2001 From: Michał Kępień Date: Wed, 5 Apr 2017 08:49:08 +0200 Subject: platform/x86: fujitsu-laptop: do not log set_lcd_level() failures in bl_update_status() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Any set_lcd_level() call can fail for one of two reasons: either requested brightness is outside the allowed range or the ACPI method used for setting brightness level is not available. For bl_update_status(), the first case is handled by backlight core, which means bl_update_status() will not even be called if requested brightness is outside the allowed range. The second case will be logged anyway by set_lcd_level() itself, so there is no point in generating another message in bl_update_status(). Remove the superfluous debug message along with a local variable that is now redundant.
