From 69a8a1961c7bf59b70ec958f8a408ba448fe62a9 Mon Sep 17 00:00:00 2001 From: Ville Syrjälä Date: Thu, 5 Jul 2018 22:00:10 +0300 Subject: drm: Skip __drm_mode_set_config_internal() on atomic drivers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Everything (apart from the actual ->set_config() call) __drm_mode_set_config_internal() does is now useless on atomic drivers.
