Hi Hans, Thanks for the patch. On 11/24/2014 10:37 AM, Hans Verkuil wrote:
From: Hans Verkuil <hans.verkuil@xxxxxxxxx> Querycap shouldn't set the version field (the core does that for you), but it should set the device_caps field. In addition, remove the CAPTURE and OUTPUT caps for M2M devices. These were already slated for removal, so it's time to do so.
