When firmware 1.20 was introduced, the dib0700 switched from a polling model using a USB control message, to the messages being delivered on a USB bulk pipe. The code I originally added would do a blocking read on the pipe with a 50ms timeout. Because the dvb-usb-remote code makes use of the global workqueue, this resulted in the global workqueue being blocked 50% of the time. Also, the synchronous urb_bulk_msg() call would burn excess CPU time (reflected as an abnormal increase in the system's load average when devices were connected). Rework the logic so that we now setup an asynchronous callback on the bulk pipe, so that we now only handle RC data when it arrives on the pipe. Note that we provide a stub function for the RC polling callback so that we can continue to leverage the shared code in dvb-usb-rc for the setting up of the input device.
