linux-next: build warning after merge of the mailbox tree

Hi all,

After merging the mailbox tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

In file included from drivers/mailbox/mailbox-mpfs.c:19:
include/soc/microchip/mpfs.h:43:12: warning: 'mpfs_blocking_transaction' defined but not used [-Wunused-function]
   43 | static int mpfs_blocking_transaction(struct mpfs_sys_controller *mpfs_client, void *msg,
      |            ^~~~~~~~~~~~~~~~~~~~~~~~~

Introduced by commit

  de5473936808 ("mbox: add polarfire soc system controller mailbox")

Hi,
That function is defined for services using the mailbox, and since 
currently none exist it is redundant. I will move it to another patch 
series that adds the services and resubmit this series.

Thanks,
Conor.
