From 8166fcead6b29589f264b9d900c0770f501964c3 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 8 Oct 2015 21:50:57 +0200 Subject: [PATCH] Revert "drm/i915: Add hot_plug hook for hdmi encoder" This reverts commit 0b5e88dc25ee6c9040c0355e6e025dcbc9c8de92. It completely breaks booting on at least bsw (and maybe more).
