Subject: [PATCH] drm/i915: fix reassignment of variable "intel_dp->DP"
This little regression was introduced by:
commit 417e822deee1d2bcd8a8a60660c40a0903713f2b
Author: Keith Packard <kei...@keithp.com>
Date: Tue Nov 1 19:54:11 2011 -0700
drm/i915: Treat PCH eDP like DP in most places
PCH eDP has many of the same needs as regular PCH DP connections,
including the DP_CTl bit settings, the TRANS_DP_CTL register.
The reachable tag for this commit is: v3.1-5461-g417e822
