The OMAP mailbox driver is used by clients to communicate with remote
processors in general. The mailbox clients are expected to have stopped
communicating with these remote processors during a system suspend. The
OMAP mailbox fifos are expected to not have any messages as such. Add a
check for any pending unprocessed messages in the suspend callback, to
detect any communication protocol issues of the mailbox clients. The
system suspend is aborted if any messages are found.
