From: Greg Kroah-Hartman Date: Thu, 29 Nov 2007 07:49:41 +0000 (-0800) Subject: Driver core: clean up debugging messages X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7dc72b2842381684b864750af31a5fb168dec764;p=openwrt%2Fstaging%2Fblogic.git Driver core: clean up debugging messages The driver core debugging messages are a mess. This provides a unified message that makes them actually useful. The format for new kobject debug messages should be: driver/bus/class: 'OBJECT_NAME': FUNCTION_NAME: message.\n Note, the class code is not changed in this patch due to pending patches in my queue that this would conflict with. A later patch will clean them up.
