Subject: linux-next: manual merge of the arm-soc tree with the mailbox tree

Hi all,

Today's linux-next merge of the arm-soc tree got a conflict in
drivers/mailbox/Kconfig between commit a1824eaab70f ("mailbox: OMAP:
introduce mailbox framework") from the mailbox tree and commit
c869c75c16b3 ("mailbox/omap: move the OMAP mailbox framework to drivers")
from the arm-soc tree.

I fixed it up (I suspect not properly - see below) and can carry the fix
as necessary (no action is required).

It looks like we have two different versions of these changes in
linux-next now, so please clean it all up.  i.e. can I just drop the
mailbox tree now?

Cheers,
