From 0c98b19fe571ede1f14bd95b855bcbe2cca99bcf Mon Sep 17 00:00:00 2001 From: Cornelia Huck Date: Thu, 31 Jan 2008 10:39:38 +0100 Subject: [PATCH] Driver core: Remove unneeded get_{device,driver}() calls. Driver core: Remove unneeded get_{device,driver}() calls. Code trying to add/remove attributes must hold a reference to the device resp. driver anyway, so let's remove those reference count games.
