Subject: [PATCH v5 06/11] media: cedrus: Cleanup control initialization
Date: Mon, 12 Aug 2019 16:35:17 -0300
Message-ID: <20190812193522.10911-7-ezequiel@collabora.com> (raw)
In-Reply-To: <20190812193522.10911-1-ezequiel@collabora.com>

In order to introduce other controls, the control initialization
needs to support an initial struct v4l2_ctrl_control.

While here, let's cleanup the control initialization,
removing unneeded fields.
