Subject: [PATCH v3 023/105] drm/vc4: crtc: Switch to of_device_get_match_data
Date:   Wed, 27 May 2020 17:47:53 +0200
Message-Id: <1ff06413a1350d28bc3e88b034ed7ad23834e5bd.1590594512.git-series.maxime@cerno.tech>

Precedence: bulk

of_device_get_match_data allow to simplify a bit the retrieval of the data
associated to the pixelvalve compatible. Let's use it.
