From f9bab55ee60d6c885eb30dab1f20827053e23355 Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Fri, 10 Nov 2017 12:34:54 +0100 Subject: [PATCH] drm/i915: Remove bogus ips_enabled check. The flag just tells us IPS can be enabled, if the primary plane is not enabled it means IPS might not be. This never triggered in CI because we don't have a haswell ULT there, but can be reproduced easily with kms_atomic_transitions.plane-all-modeset-transition Signed-off-by: Maarten Lankhorst Link: https://patchwork.freedesktop.org/patch/msgid/20171110113503.16253-2-maarten.lankhorst@linux.intel.com [mlankhorst: Remove from haswell_get_pipe_config too.
