From bc8f0a26855d8fac68040d462ec3cc13884e98e5 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 14 Feb 2007 21:15:05 +0100 Subject: [PATCH] hwmon/abituguru: Fix unchecked return status Fix an unused return value warning for the abituguru driver. Also make sure the sysfs files are created before we register with the hwmon class, and delete the sysfs files on driver removal.
