From 69a44b16cba895ff761c1763508c271a084950b5 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Mon, 26 Sep 2016 12:20:46 +0300 Subject: [PATCH] drm/i915: Add spurious CRT DMI match for Intel DZ77BH-55K MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Intel DZ77BH-55K board doest't have a physical VGA connector, and yet it always detects that something is connected there. Add it to the DMI blacklist to ignore the spurious detection results. Allows me to drop 'video=VGA-1:d' from my kernel cmdline.
