From b6e5b8f1a90230f922de8af59cdaf1ad83e1ac1e Mon Sep 17 00:00:00 2001 From: Ricardo Ribalda Date: Fri, 20 Mar 2015 10:45:43 -0300 Subject: [PATCH] [media] media: New flag V4L2_CTRL_FLAG_EXECUTE_ON_WRITE Create a new flag that represent controls which its value needs to be passed to the driver even if it has not changed. They typically represent actions, like triggering a flash or clearing an error flag. So writing to such a control means some action is executed.
