From 4ad275e5cb576fa4e3e12597cb81eed0d500416d Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Thu, 11 Aug 2011 14:36:33 -0400 Subject: [PATCH] dynamic_debug: Convert printks to pr_ Add pr_fmt(fmt) with __func__. Converts "ddebug:" prefix to "dynamic_debug:". Most likely the if (verbose) outputs could also be converted from pr_info to pr_debug.
