[PATCH 106/196] kobject: clean up debugging messages

Greg Kroah-Hartman
2008-01-25T07:57:50Z

The kobject debugging messages are a mess. This provides a unified
message that makes them actually useful.

The format for new kobject debug messages should be:
kobject: 'KOBJECT_NAME' (ADDRESS): FUNCTION_NAME: message.\n
