From f3269058e7a80083dcdf89698bfcd1a6c6f8fd12 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 24 Jan 2011 15:17:08 +0000 Subject: [PATCH] drm/i915/crt: Force the initial probe after reset Upon resume, like after a cold boot, we need to forcibly probe the analog connector and cannot rely on the hotplug status. Based on a patch by Takashi Iwai.
