Subject: [PATCH v3 027/105] drm/vc4: crtc: Turn static const variable into a define
Date:   Wed, 27 May 2020 17:47:57 +0200
Message-Id: <8535c679f79af8abaa1b7796261bfeda11f874fd.1590594512.git-series.maxime@cerno.tech>

The hvs_latency_pix variable doesn't need to be a variable and can just be
defined.
