Subject: v4l2-ctl: if V4L2_CTRL_FLAG_UPDATE is set, use G/S_EXT_CTRLS Author: Hans Verkuil <hans.verk...@cisco.com> Date: Fri Jun 29 11:35:00 2018 +0200 This flag indicates that this control influences other controls, so use G/S_EXT_CTRLS in that case to be atomic when setting and getting such controls. E.g. this is relevant when setting both the gain and autogain for an auto-cluster.
