+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
