From 30943e1484aab78d83ddfb706bca65c5d8092bfb Mon Sep 17 00:00:00 2001 From: =?utf8?q?Micha=C5=82=20K=C4=99pie=C5=84?= Date: Fri, 7 Apr 2017 15:07:12 +0200 Subject: [PATCH] platform/x86: fujitsu-laptop: do not log LED registration failures MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit If acpi_fujitsu_laptop_leds_register() returns an error, the latter will become the return value of acpi_fujitsu_laptop_add(), which in turn will be reported by driver core. Simplify code by replacing pr_err() calls with return statements. Return 0 instead of result when no errors occur in order to make the code easier to read.
