From c6dea929a4951c3c048554a1ef54cf8143d9577a Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Mon, 3 Mar 2014 17:00:57 +0100 Subject: config_odev_add*_attribute: Don't add the attribute to the list twice Don't do the xorg_list_append a 2nd time when updating existing attributes, while at it add a helper function for this to avoid code duplication.
