-Subject: [PATCH] spi: Check to see if the device is processing a message
- before we idle
-
-cur_msg is updated under the queue lock and holds the message we are
-currently processing. Since currently we only ever do removals in the
-pump kthread it doesn't matter in what order we do things but we want
-to be able to push things out from the submitting thread so pull the
-check to see if we're currently handling a message before we check to
-see if the queue is idle.
