Subject[PATCH 07/11] uml ubd driver: reformat ubd_config
Date
From: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it>

Pure whitespace and style fixes split out from subsequent patch. Some changes
(err -> ret) don't make sense now, only later, but I split them out anyway since
they cluttered the patch.
