Subject: [PATCH 11/12] drm/exynos: Remove custom FB helper deferred setup
Date: Wed, 21 Jun 2017 20:28:14 +0200	[thread overview]
Message-ID: <20170621182815.14602-12-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <20170621182815.14602-1-daniel.vetter@ffwll.ch>

From: Thierry Reding <treding@nvidia.com>

The FB helper core now supports deferred setup, so the driver's custom
implementation can be removed.

v2: Drop NULL check, drm_fb_helper_hotplug_event handles that already.
