From 19ec135838f032ad1aa0610b173ad78c16d53d47 Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Wed, 2 Feb 2011 12:28:02 -0800 Subject: [PATCH] drm/i915: don't check plane vs pipe enable on ILK+ These bits have a different meaning on ILK+, where planes are hardwired to pipes. Fixing this avoid some spurious assertion failures.
