Subject: linux-next: build failure after merge of the powerpc-mpe tree

Hi all,

After merging the powerpc-mpe tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:


In file included from arch/powerpc/platforms/powernv/setup.c:36:0:
arch/powerpc/include/asm/opal.h:214:17: error: 'enum OpalMessageType' declared inside parameter list [-Werror]
          struct notifier_block *nb);
                 ^

Caused by commit d7cf83fcaf1b ("powerpc/powernv: Move opal-api.h closer
to the Skiboot version") interacting with commit b921e90260ce
("powerpc/powernv: Add OPAL message notifier unregister function") from
the powerpc tree.

I have added the following merge fix patch:
