From c56769c92f684d708b05052ec4f4555ea25da4de Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 7 Jun 2012 08:59:49 +0200 Subject: [PATCH] drm/i915: enable edp vdd in intel_dp_detect We need this for dp aux communication. This issue can fill the dmesg with WARN spam when the panel is disable (e.g. while reconfiguring the mode or while resuming).
