Subject: [PATCH 2/5] media: New flag V4L2_CTRL_FLAG_EXECUTE_ON_WRITE
Date: Thu, 19 Mar 2015 16:21:23 +0100 [thread overview]
Message-ID: <1426778486-21807-3-git-send-email-ricardo.ribalda@gmail.com> (raw)
In-Reply-To: <1426778486-21807-1-git-send-email-ricardo.ribalda@gmail.com>
Create a new flag that represent controls that represent controls that
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.
