staging: unisys: visorbus: return EAGAIN when empty It really isn't an error when you call visorchannel_signalremove and there isn't anything in the queue. Just means that the IOSP didn't process anything since the last time you checked. Just inform the caller that it is empty by returning -EAGAIN.
