From 812fc6f2a8b791c2449457a90eb21afbad489680 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Thu, 6 Jul 2017 15:00:22 +0200 Subject: [PATCH] drm/exynos: Remove custom FB helper deferred setup 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.
