From 6d369e8f226594632ce4260129509daf7030de0a Mon Sep 17 00:00:00 2001
From: Khem Raj <raj.khem@gmail.com>
Date: Mon, 9 May 2016 22:03:57 +0000
Subject: [PATCH] mdadm.h: Undefine dprintf before redefining
dprintf is also defined in libc see
usr/include/bits/stdio2.h, this comes into
play especially when fortify sources is enabled
and compilers like clang reports the override
In file included from policy.c:25:
./mdadm.h:1562:9: error: 'dprintf' macro redefined [-Werror,-Wmacro-redefined]
^
/mnt/oe/openembedded-core/build/tmp-glibc/sysroots/qemux86/usr/include/bits/stdio2.h:145:12: note: previous definition is here
