From 45f014c5264f5e68ef0e51b36f4ef5ede3d18397 Mon Sep 17 00:00:00 2001 From: Ricardo Ribalda Date: Fri, 20 Mar 2015 10:55:37 -0300 Subject: [PATCH] [media] media/v4l2-ctrls: Always execute EXECUTE_ON_WRITE ctrls Any control with V4L2_CTRL_FLAG_EXECUTE_ON_WRITE set should return changed == true in cluster_changed. This forces the value to be passed to the driver even if it has not changed.
