From 673fae90d5ee4ae2b6403f9d45af7ff640f06a60 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Sat, 13 Mar 2010 23:49:13 -0800 Subject: [PATCH] firmware loader: rely on driver core to create class attribute Do not create 'timeout' attribute manually, let driver core do it for us. This also ensures that attribute is cleaned up properly.
