From: Rasmus Villemoes <linux@xxxxxxxxxxxxxxxxxx> Subject: dynamic_debug: consolidate DEFINE_DYNAMIC_DEBUG_METADATA definitions Instead of defining DEFINE_DYNAMIC_DEBUG_METADATA in terms of a helper DEFINE_DYNAMIC_DEBUG_METADATA_KEY, that needs another helper dd_key_init to be properly defined, just make the various #ifdef branches define a _DPRINTK_KEY_INIT that can be used directly, similar to _DPRINTK_FLAGS_DEFAULT.
