+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.
