Subject: [PATCH 65/89] drm/vc4: hdmi: Rename hdmi to vc4_hdmi
Date:   Mon, 24 Feb 2020 10:07:07 +0100
Message-Id: <a4ebd977130db384dd720d5be8ffd886a9175ffe.1582533919.git-series.maxime@cerno.tech>
In-Reply-To: <cover.6c896ace9a5a7840e9cec008b553cbb004ca1f91.1582533919.git-series.maxime@cerno.tech>
References: <cover.6c896ace9a5a7840e9cec008b553cbb004ca1f91.1582533919.git-series.maxime@cerno.tech>

Precedence: bulk

The driver isn't consistent with the name given to the vc4_hdmi
structure pointer in its functions. Make sure to use a consistent name.
