Subject: [PATCH 2/2] drm/i915: Simplify DP port limited color range bit platform checks
Date: Mon, 14 Nov 2016 19:44:07 +0200 [thread overview]
Message-ID: <1479145447-12907-3-git-send-email-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <1479145447-12907-1-git-send-email-ville.syrjala@linux.intel.com>
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
Instead of checking for everything not supporting the limited color
range bit in the DP port register, let's check for the one thing
that does have it (g4x).
