[PATCH v2 2/5] media: New flag V4L2_CTRL_FLAG_EXECUTE_ON_WRITE

From: Ricardo Ribalda Delgado
Date: Fri Mar 20 2015 - 09:45:54 EST


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.
