The patch titled
Subject: dynamic_debug: move pr_err from module.c to ddebug_add_module
has been removed from the -mm tree. Its filename was
dynamic_debug-move-pr_err-from-modulec-to-ddebug_add_module.patch
This patch was dropped because it was merged into mainline or a subsystem tree

Subject: dynamic_debug: move pr_err from module.c to ddebug_add_module
This serves two purposes: First, we get a diagnostic if (though extremely
unlikely), any of the calls of ddebug_add_module for built-in code fails,
effectively disabling dynamic_debug. Second, I want to make struct
_ddebug opaque, and avoid accessing any of its members outside
dynamic_debug.[ch].
