Subject: [PATCH 152/196] 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.
