From ceb9190969e458dcd1427566f762dbb9cfdfdc94 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 29 Sep 2017 12:31:20 +0900 Subject: [PATCH] dm: replace dm_dbg() with pr_debug() As we discussed before in ML, dm_dbg() causes undefined reference error if #define DEBUG is added to users, but not drivers/core/util.c We do not need this macro because we can use pr_debug() instead, and it is pretty easy to enable it for the DM core by using ccflags-y.
