From d6843dda38dfa6dec213786d514051af34c9b84c Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Wed, 2 Sep 2020 17:30:23 +0300 Subject: [PATCH] drm/i915: remove the extra modeset init layer MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Streamline the modeset init by removing the extra init layer. No functional changes, which means the cleanup path looks hideous.
