From: Rasmus Villemoes <linux@xxxxxxxxxxxxxxxxxx>
Subject: lib/dynamic_debug.c: introduce accessors for string members of struct _ddebug
When we introduce compact versions of these pointers (a la
CONFIG_GENERIC_BUG_RELATIVE_POINTERS), all access to these members must go
via appropriate accessors. This just mass-converts dynamic_debug.c to use
the new accessors.
