[PATCH 3/3] FS/QNX6: update debugging to current functions.
From: Fabian Frederick
Date: Thu Jun 05 2014 - 14:15:08 EST
This patch adds DDEBUG in Makefile when CONFIG_QNX6FS_DEBUG is set.
All QNX6DEBUG messages are replaced by pr_debug which means
debugging will be emitted in debug level only and no more in error
and info levels.
debug uses now pr_fmt and __func__
QNX6DEBUG definition has been removed.
