Subject: [PATCH v2 2/9] drm/fb-helper: Reshuffle code for subsequent patches
Date: Tue,  7 Jun 2016 17:26:18 +0200	[thread overview]
Message-ID: <20160607152625.9511-3-thierry.reding@gmail.com> (raw)
In-Reply-To: <20160607152625.9511-1-thierry.reding@gmail.com>

From: Thierry Reding <treding@nvidia.com>

An unlocked version of the drm_fb_helper_add_one_connector() function
will be added in a subsequent patch. Reshuffle the code separately to
make the diff more readable later on.
