Subject: [PATCH v4 1/3] media: stm32-dcmi: improve sensor subdev naming
Date: Wed, 31 Jul 2019 14:56:21 +0200	[thread overview]
Message-ID: <1564577783-18627-2-git-send-email-hugues.fruchet@st.com> (raw)
In-Reply-To: <1564577783-18627-1-git-send-email-hugues.fruchet@st.com>

Rename "subdev" entity struct field to "source"
to prepare for several subdev support.
Move asd field on top of entity struct.

Signed-off-by: Hugues Fruchet <hugues.fruchet@st.com>
