[PATCH 1/1] driver-core: Shut up dev_dbg_reatelimited() withoutDEBUG

From: Hiroshi Doyu
Date: Mon Aug 20 2012 - 06:49:19 EST


dev_dbg_reatelimited() without DEBUG printed "217078 callbacks
suppressed". This shouldn't print anything without DEBUG.

With CONFIG_DYNAMIC_DEBUG, the print should be configured as expected.
