Subject: [PATCH v4 03/11] drm/fb-helper: Improve code readability
Date: Wed, 29 Mar 2017 16:43:53 +0200 [thread overview]
Message-ID: <20170329144401.1804-4-thierry.reding@gmail.com> (raw)
In-Reply-To: <20170329144401.1804-1-thierry.reding@gmail.com>
From: Thierry Reding <treding@nvidia.com>
Add a couple of temporary variables and use shorter names for existing
variables in drm_fb_helper_add_one_connector() for better readability.
