Subject: [PATCH RFC 08/11] media: vidtv: properly initialize the internal state struct
Date:   Mon, 14 Sep 2020 11:03:23 +0200
Message-Id: <22b323ff01a900c01bf9e407c4130f82f62fe312.1600073975.git.mchehab+huawei@kernel.org>

Precedence: bulk

Right now, the config data passed from the bridge driver is
just ignored.

Also, let's initialize the delayed work at probing time.
